The neck injury that cut short Seattle Seahawks running back Chris Carson's 2021 season has ultimately ended his career. 

Carson decided to retire on Tuesday after five NFL seasons, according to NFL Network Insider Ian Rapoport. 

The 27-year-old had failed his physical and the Seahawks are officially releasing him with a failed physical designation, which under the collective bargaining agreement allows Carson to receive several million dollars in injury protection benefits. 

Carson had been hopeful of being healthy enough to play this year after being sidelined since Week 4 of the 2021 season with the serious neck injury. 

When healthy, Carson was one of the top running backs in the league, ranking fifth in rushing yards in 2018 with 1,151 yards and fifth again a year later with a career-high 1,230 yards. 

A seventh-round pick by the Seahawks in 2017, Carson finishes his career with 3,502 rushing yards with 24 rushing touchdowns. 

Upon Carson's retirement, Rashaad Penny and rookie Kenneth Walker III will handle the running back duties for a Seattle team that expects to rely heavily on the ground game with Geno Smith and Drew Lock competing for the starting quarterback job after Russell Wilson was traded to the Denver Broncos. 

Penny led the Seahawks with 749 rushing yards last season and his average of 6.29 yards per attempt was the highest in the NFL among all players with a minimum of 100 carries. 

Cincinnati Bengals quarterback Joe Burrow is undergoing surgery to have his appendix removed, NFL Network's Ian Rapoport said Tuesday.

Burrow is expected to miss practice time during training camp but make a full recovery before the defending AFC champion Bengals begin their season on September 11 against the visiting Pittsburgh Steelers.

The news comes one day after team owner Mike Brown said Cincinnati's "whole focus" is to get an extension in place with Burrow, who is eligible to negotiate a new deal after this season – his third in the NFL.

"Right now our obvious, most important issue will be our quarterback," Brown said on Monday. "It's not quite ready or ripe yet, but it's right down the track and we see the train coming."

Burrow went 2-7-1 as the starter in 2020 after the Bengals selected him with the No. 1 overall pick in the NFL Draft. He tore his left ACL and MCL in Week 11 that season before returning last year and leading Cincinnati to their first playoff berth since 2015 and first Super Bowl appearance since 1988.

The Bengals led the Los Angeles Rams 20-13 in the third quarter of the Super Bowl before eventually losing 23-20. Burrow passed for 263 yards with a touchdown and no interceptions against the Rams.

"We couldn't be happier with Joe Burrow," Brown said. "He's everything you would wish for, especially for a quarterback in Cincinnati. And our whole focus is going on keeping him here."

The Chicago Bears have bolstered their offensive line, signing veteran tackle Riley Reiff to a one-year deal that will likely pay him $10million, according to ESPN’s Adam Schefter. 

The deal, which was reported on Tuesday, could be worth up to $12.5million. 

Considered one of the best free agents still on the market, Reiff started 12 games for the Cincinnati Bengals in 2021 before an ankle injury ended his season. 

Since being drafted 23rd overall by the Detroit Lions in 2012, the 33-year-old Reiff has appeared in 147 games with 139 starts. This will be his third NFC North team after spending his first five seasons with the Lions and the next four with the Minnesota Vikings, with whom he signed as a free agent prior to the 2017 season. 

Reiff is expected to win the starting left tackle job for a Bears team that struggled mightily to protect Justin Fields in his 2021 rookie season. 

The Chicago offensive line allowed a league-worst 58 sacks last season with Fields being sacked on 11.8 per cent of his dropbacks – the worst rate in the NFL among quarterbacks with at least 250 pass attempts. 

San Francisco 49ers players are scheduled to report to training camp on Tuesday, and coach Kyle Shanahan expects star wide receiver Deebo Samuel to attend despite his ongoing contract dispute. 

Shanahan is also certain Samuel will get a new deal soon. 

"What I do know is: I'm not worried about it not getting done," he told The Athletic. "I feel very confident that Deebo's going to be on our team this year, and he's going to be for many years after. I do believe he'll get a deal. I know that they're working on it right now."

Shanahan said general manager John Lynch and the 49ers front office have been working with Samuel's agent, Tory Dandy, on a new deal over the past few weeks. 

Samuel emerged as a dangerous playmaker lined up both as a receiver and in the backfield for San Francisco last season, earning All-Pro honours with 1,770 scrimmage yards and 14 total touchdowns. 

Due to make $3.986million in the final year of his rookie contract in 2022, the 26-year-old Samuel requested a trade after the 49ers failed to sign him to an extension earlier this offseason.

"I think every player in the league is underpaid," Shanahan said. "I think this league makes a lot of money, and these players go through a lot of stuff, so like you always look at it that way.

"But when you become a head coach or a general manager and stuff like that, you do get to see the other side, and your job is to put the best football team together possible, and so you work with these players and your goal is to get them paid, [but you] got to balance all that stuff together so you have a chance to win."

The 49ers reached the Super Bowl in Samuel's 2019 rookie season and nearly made it again last year before losing to the eventual champion Los Angeles Rams in the NFC Championship Game. 

This year's offense will have a different look, however, with Trey Lance taking over at quarterback for Jimmy Garoppolo. 

Despite Samuel's contract dispute, he still attended mandatory minicamp and is expected to be at training camp because of the collective bargaining agreement that deters players from holding out. 

"The days of holding out and stuff are a little bit different now because players, regardless of what the team decides later, always have to pay [the fines] back," Shanahan said. "Now, those fines can't get paid back." 

After helping the Los Angeles Rams win Super Bowl LVI in February, Aaron Donald reportedly considered walking away from football at the top of his game. 

He, obviously, ended up not retiring, with the Rams ultimately restructuring his contract to give him a record payday in early June. 

But from the time the Rams raised the Lombardi Trophy to the time Donald agreed to the massive raise, coach Sean McVay says his ongoing conversations with the future Hall of Famer were crucial in getting a deal done. 

"My dialogue with Aaron throughout the process I thought was key to be able to feel good about it but also understand what needed to get done to have him come back and lead the way for us," McVay said on Monday. 

Donald’s restructured deal guarantees him $95million over the next three years, making him the highest-paid non-quarterback in NFL history. 

The hefty price is justified, however, given he’s widely considered one of the best defensive players in NFL history. 

A Super Bowl championship was the last major accomplishment left to achieve for the 31-year-old Donald, who has three Defensive Player of the Year Awards and seven consecutive First Team All-Pro selections on his resume. 

So McVay understood why Donald wanted to take some time to evaluate his career after playing a vital role in the Rams’ Super Bowl victory over the Cincinnati Bengals with a pair of sacks against Joe Burrow. 

"When you reach (and win the Super Bowl), when he had been working so hard to try to get to that goal, there's an exhale," McVay said. "I think you want to be able to let the dust settle, figure out what's important. What can we do to accommodate that? If you still want to be able to play football."

Donald still has the passion to play and McVay credits their conversations as a big reason why one of the most feared defensive players ever will be suiting up for the Rams in their quest to repeat as Super Bowl champions. 

"(Donald and I) had great dialogue throughout the course of the offseason," McVay said. "I think like anything else, it's such a long process when you're able to play 21 games and if you include the pre-season, you're talking about 24 games last year. So many emotions."

After spending much of his offseason recovering from a right elbow injury, veteran quarterback Matthew Stafford resumed throwing as the Los Angeles Rams opened training camp on Sunday.  

"It feels good to get out there," Stafford said. "Definitely knocking some rust off and feeling it again. It's good to get out there and stress it a little bit and see how it reacts."

Stafford, who helped lead the Rams to a Super Bowl title last season, has rested his arm since February and received an anti-inflammatory injection in his elbow. 

Stafford and head coach Sean McVay have said that the 14th-year quarterback will have to ease back into a full workload after taking so much time off. 

"It's an interesting thing trying to have a little bit of governor on there, and at the same time, just trying to be as smart as I can," Stafford said. "It's a process. Just going to have to sit there and work through it, trust it. We'll figure it out as we go."

McVay told reporters that while Stafford is on a pitch count, it didn’t come into play in Sunday’s camp-opening session. 

"[Stafford] was a full participant today," McVay said. "Like him having as much experience as he does, we will continue to build him up.

"We're aware of what that pitch count is, but it didn't restrict him from being able to do anything today."

Acquired last offseason from the Detroit Lions, Stafford was a key reason why the Rams got over the hump to win their first Super Bowl since the 1999 season. 

Stafford tied a career high last season with 41 touchdown passes and registered a 102.9 passer rating, starting all 17 games. 

He added nine more touchdown passes during the Rams’ postseason run, including six to Super Bowl MVP Cooper Kupp. 

The Tampa Bay Buccaneers have appeared to have found their replacement for the retired Rob Gronkowski, signing tight end Kyle Rudolph to a one-year contract on Monday.

The deal is reportedly worth $2million and Rudolph can earn an additional $1.5million in incentives.

Gronkowski retired for the second time in his career last month despite having the chance to play another season with Tom Brady, who announced his retirement on Feb. 1 before changing his mind March 13 and returning to Tampa Bay.

In Rudolph, the Buccaneers land a tight end who had 26 catches for 257 yards and one touchdown last season for the New York Giants.

That was Rudolph’s only year with New York after spending his first 10 seasons with the Minnesota Vikings, who selected him with the 11th pick of the second round (43rd overall) in the 2011 NFL Draft.

Rudolph earned two Pro Bowl selections while playing for Minnesota, including being named the MVP of the game in 2012 after having five catches for 122 yards and a touchdown.

Rudolph has appeared in 156 regular-season games, hauling in 479 passes for 4,745 yards and 49 TDs.

Raheem Mostert has confirmed he is fit to feature in the Miami Dolphins' training camp.

Mostert has been out of action since Week 1 of last season due to a knee injury.

The running back and his team-mates are scheduled to report for training camp on Tuesday, and on Monday Mostert used his official Twitter account to declare his fitness.

"Wanted to give you all an update," he wrote on Monday. "Yah Boy is CLEARED!!! It's go time!!"

Mostert has been rehabbing his knee since chipping cartilage in the San Francisco 49ers' 2021 season opener.

He underwent surgery in October and signed a one-year contract with Miami this offseason, reuniting him with first-year coach Mike McDaniel, who served as the 49ers' run game coordinator as well as offensive coordinator in San Francisco from 2017 to 2021.

"Being told you may never step on the field again isn't easy to hear," Mostert went on to write. "But when you bet on yourself, your faith, your determination, and modern medicine, good things happen. Hard work pays off! Beyond thankful!!"

The 30-year-old enjoyed his best season with the 49ers in 2019, when he rushed for 772 yards and eight touchdowns with an average of 5.6 yards per carry – the best by a running back with a minimum of 100 attempts – but injuries have limited him to just nine games these past two seasons.

Now entering his eighth season, Mostert is one of three new running backs signed by the Dolphins this offseason, along with Sony Michel, who led the Super Bowl-winning Los Angeles Rams with 845 rushing yards last year, and Chase Edmonds, who rushed for 592 yards and averaged 5.1 yards per carry last season for the Arizona Cardinals.

The Dolphins, who brought back Myles Gaskin and Salvon Ahmed from last year's backfield, struggled mightily to move the ball on the ground last season as only the Houston Texans averaged fewer yards per carry than Miami's average of 3.55 and had fewer plays of 10+ rushing yards than Miami's 34.

Known for his speed, Mostert led all running backs with a minimum of 100 rushes in 2019 in percentage of carries gaining at least 10 yards at 16.8 per cent.

After seemingly implying that Derek Carr is a Hall of Fame quarterback, Las Vegas Raiders wide receiver Davante Adams pumped the breaks on writing his presentation speech for his new team-mate's induction into the NFL Hall of Fame.

During an interview on CBS Sports on Friday, Adams was asked about moving on from Aaron Rodgers and the Green Bay Packers to his new quarterback in Carr.

"Anytime you change quarterbacks from Hall of Famer to Hall of Famer… it's going to be a little bit of an adjustment," he replied.

It certainly sounded like he was saying that the four-time league MVP and a Super Bowl MVP Rodgers – who had 37 touchdown passes to only four interceptions in 2021 for his eighth season of 30 or more TD passes – and Carr – who had 23 TD passes to 14 interceptions in 2021 and has not thrown more than 30 TD passes in a season since 2015 – both belong in the Hall of Fame.

Adams clarified that initial comparison and acknowledged he meant it is going to be an adjustment whenever you change quarterbacks.

"What I meant to say was even if you go Hall of Famer to Hall of Famer it's an adjustment," he said.

"Even if it is Hall of Famer to Hall of Famer, there's going to be an adjustment. I wasn't saying Hall of Famer Aaron to Hall of Famer Derek."

While he was quick to see how his original remarks could have been misinterpreted, he still believes his new quarterback could one day join Rodgers in the Hall of Fame.

"What I'm not going to do is take away from that statement because, why is Derek not a Hall of Famer? What I meant, I left one key word out of there because that's not exactly what I meant," he said.

"But I do think that Derek's career is Hall of Fame-worthy, and why not? Does he have the MVPs right now? No. Has he won a Super Bowl? Not yet. That's obviously what we're chasing."

Entering his ninth season in the NFL – all with the Raiders – Carr appeared in his first playoff game this past January – a 26-19 loss to the Cincinnati Bengals in which he threw an interception near the goal line in the final seconds.

Carr is a three-time Pro Bowler and the Raiders’ all-time leader in passing yards and passing touchdowns, but he has not had a receiver as dynamic as Adams in recent years.

A five-time Pro Bowler, Adams had career highs of 123 receptions for 1,553 yards last season while also catching 11 touchdowns after hauling in 18 in 2021.

The 29-year-old receiver signed a five-year, $141.25million contract extension after being traded to the Raiders this offseason and is now reunited with his former Fresno State team-mate in Carr as they look to help the franchise to its first postseason win since reaching the Super Bowl in the 2002 season.

"But what I'm not going to do is say Derek is not going to be a Hall of Famer because at the end of the day I believe, and this is not putting any expectations or any added pressure on him because he puts that type of pressure on himself because of what he expects every time he touches the field," Adams said.

"But yeah, I did not mean to say exactly that. I'm going to reiterate, even if you go from Hall of Famer to even another Hall of Famer, it's going to be an adjustment. Any time you change quarterbacks, is what I was getting at. So, take that and run with it and do whatever you want to do with it."

The XFL announced on Sunday that it will return in 2023 with the league revealing the home cities, and head coaches for each team.

Owners Dwayne Johnson and longtime business partner Dany Garcia announced that the eight teams competing next year will be Arlington, Houston, San Antonio, Orlando, Las Vegas, Seattle, St. Louis and Washington, D.C.

Originally founded in 2001 by WWE’s Vince McMahon and relaunched in 2020, the XFL went bankrupt due to the COVID-19 pandemic and its future was uncertain. Johnson and Garcia then purchased the league in August 2020.

Longtime Oklahoma coach Bob Stoops will coach Dallas, former NFL head coach Wade Phillips will coach Houston and former Steelers receiver Hines Ward is the San Antonio coach.

Las Vegas will be coached by 17-year NFL veteran Rod Woodson, Seattle’s coach is former Rams and Saints coach Jim Haslett, former NFL cornerback Terrell Buckley will be Orlando’s coach, former NFL tight end Anthony Becht is St. Louis’ coach and Washington will be coached by Reggie Barlow, who played seven seasons in the NFL as a receiver.

The XFL is expected to kick off on February 18, 2023.

Buffalo Bills offensive lineman Rodger Saffold hurt his ribs in a recent car accident and has been placed on the non-football injury list, coach Sean McDermott announced.

The 34-year-old Saffold joined Buffalo on a one-year contract in March after he was released by the Tennessee Titans following a 2021 season in which he earned his first Pro Bowl selection. The move saved Tennessee over $10million in salary cap space.

Saffold's setback was revealed as the Bills opened their training camp on Sunday.

McDermott said: "Rodger Saffold will start on the NFI list. Rodger injured some ribs in a car accident recently, so he'll start on NFI."

Saffold was the first pick in the second round of the 2010 NFL Draft by the St. Louis Rams. He spent his first nine seasons with the Rams before signing a four-year, $44million deal with the Titans in 2019.

Saffold’s 160 games since 2010 are tied for the fourth-most among active offensive linemen in the NFL over that span.

McDermott said he expected Saffold to "be back in due time".

Forecasting which players will break out in a given NFL season is a difficult exercise.

New stars can come from anywhere. Highly drafted rookies can swiftly justify their selection, while others who have endured a less linear path to the highest level often emerge from the wilderness to become well-known names.

But, for those players who have already had the benefit of experience in the league, Stats Perform can look at the data to judge who is in a spot to potentially make the jump to stardom.

Such ascents are regularly a product of situation. Here we look at three offensive players and three defenders who find themselves in spots conducive to a possible breakout year in 2022.

Jalen Hurts - Philadelphia Eagles

Hurts making the leap in his third season in the league is largely contingent on how his skill set is utilised by the Eagles.

Playing behind an excellent offensive line that ranked fifth in pass-block win rate last season and with a host of playmakers now including A.J. Brown, Hurts looks set up for success in 2022.

But for that success to be realised, the Eagles must tailor their offense to what he does well. In 2021, where Hurts clearly excelled was in the play-action game. Hurts produced a well-thrown ball on 80.4 per cent of play-action pass attempts, averaging 16.78 air yards on those throws.

Though they averaged 9.2 yards per play when they ran play-action, the Eagles did so on only 13.07% of their passing plays. By contrast, they ran straight dropback pass plays on 39.21% of snaps but averaged just 7.35 yards per play. Philadelphia went to the quick game on 21.57% of snaps with an average of 5.31 yards per play.

Having acquired Brown, who thrived playing in a heavy play-action offense with the Tennessee Titans, the Eagles must lean more into the play-action looks to give Hurts the best chance of improving on a quietly efficient 2022.

It would not be a seismic shift in their offensive approach, but with the talent level on their roster, it is one that could propel the Eagles to a deep playoff run and allow Hurts to end questions about his legitimacy as the long-term starter.

Brandon Aiyuk - San Francisco 49ers

Drafted from the star-studded receiver class of 2020, Aiyuk has not produced at the same level of Justin Jefferson, CeeDee Lamb and Tee Higgins.

That is partly a product of the many mouths there are to feed in the San Francisco offense and partly a result of him falling out of favour with head coach Kyle Shanahan early last season.

However, Aiyuk worked his way back to being a focal point of the Niners offense down the stretch in 2021, producing a string of key plays during their surge into the postseason.

Aiyuk produced a big play on 40.8% of his 98 targets last season – fourth among wide receivers with at least 50 targets in 2021. Delivering a burn, which is when a receiver wins his matchup with a defender on a play where he is targeted, on 65.3% of his targets, his 16 receptions of 20 yards or more were tied for 12th in the NFL.

His numbers in that regard appear likely to improve as the 49ers transition from Jimmy Garoppolo to Trey Lance at quarterback. Only one quarterback with a minimum of 50 attempts last season – Drew Lock (10.20) – averaged more air yards per attempt than Lance (10.10). Garoppolo’s 7.38 per attempt was below the league average of 7.99.

Aiyuk is an excellent route runner who brings yards-after-the-catch upside and has already shown signs of building a rapport with Lance, catching four passes for 94 yards in the 2021 third overall pick’s second start against the Houston Texans. 

If that rapport is furthered with a quarterback who should greatly improve the downfield threat posed by the San Francisco passing attack, 2022 could be the season in which Aiyuk establishes himself as another gem from a receiver class that has already emphatically lived up to its billing.

David Njoku - Cleveland Browns

The Browns have been waiting for an Njoku breakout since drafting him in the first round in 2017, and they are seemingly banking on it coming in the near future.

Cleveland signed Njoku to a four-year, $56.75 million extension this offseason having initially placed the franchise tag on the former Miami Hurricanes tight end. Those moves were made despite Njoku having a career-high in receiving yards of 639, which was in 2018.

Njoku has struggled with injuries – never starting more than 14 games in a season – but there’s evidence to suggest this will be the year he puts it all together. Last season, Njoku had a mediocre burn rate of 57.7%, but Rob Gronkowski (12.87) and Dallas Goedert (12.39) were the only tight ends with at least 25 targets to average more burn yards per target.

He was tied for 10th in burn yards per route (2.3) and 14th in big play rate (29.9%) and, assuming he stays healthy, will likely be the number two target behind Amari Cooper for the Browns in 2022.

The Browns' offense has recently been built around the running ability of Nick Chubb and Kareem Hunt, but Deshaun Watson (if and when he is allowed to play) offers the passing game a significantly higher ceiling.

With the Browns’ wide receiver options beyond Cooper lacking in experience, Njoku stands to benefit greatly from that additional upside through an increased target share and the efficiency numbers from 2021 paint the picture of a player who will take advantage of his extra opportunities.

Christian Barmore - New England Patriots

New England suffered a self-inflicted talent drain in the secondary, but the impact of the loss of J.C. Jackson and Co. may be minimised if the Patriots can get more from the defensive front.

The Patriots were seventh in pass-rush win rate last year, so it is fair to question how much more of a jump they can make in that regard. But Barmore is the one who may fuel such a leap.

New England's second-round pick from 2021 had just 1.5 sacks last season. However, he ranked eighth among defensive tackles with at least 100 one-on-one pass rush matchups with a stunt-adjusted win rate of 38.34%.

He achieved a top-10 finish in that metric despite being double-team blocked 127 times. Only seven defenders were double teamed more often. 

Converting those pass-rush wins into sacks will be the aim in 2022 and, if he continues to dominate his matchups in his second year and the Patriots get the consistency from edge rushers Matthew Judon and Josh Uche to reduce the number of double teams, Barmore's production should see a significant improvement.

Pete Werner - New Orleans Saints

Off-ball linebackers might not move the needle like they once did, but Werner is set to step into a starting role alongside Demario Davis on a Saints defense that is still expected to be among the best in the NFL.

Werner allowed a burn on 13 of his 27 targets in coverage, and his ratio of 48.1% was above the league average for linebackers with at least 25 targets (50.8).

His burn yards per target allowed average of 8.08 yards was 18th for the players at his position to meet that threshold. Werner allowed a big play on 17.4% of his targets, also putting him comfortably on the right side of the ledger for that metric (the average was 19.8%).

On top of that, his run disruption rate of 12.1% was eighth for all linebackers with a minimum of 50 run defense snaps.

In a hugely encouraging rookie year, Werner proved he is ready to step up to the starting role.

Playing on a defense stacked with talent on the front and in the secondary, he is in a situation to make a massive impact for a unit that may have to carry the load if the Saints are to return to the playoffs in 2022.

Rashad Fenton - Kansas City Chiefs

The Chiefs suffered an underrated loss in free agency as cornerback Charvarius Ward departed for San Francisco. Ward allowed a burn on just 39.8% of targets in 2021 – the fourth-best rate among corners with at least 50 targets.

His departure will likely see Fenton and L'Jarius Sneed start at corner this season, though the Chiefs did add Trent McDuffie to their secondary in the draft.

The numbers indicate Fenton will rise to the challenge. He was second in burn yards per target (7.71) and third in burn yards per snap (1.22) allowed last year (min. 50 targets).

He gave up a big play on just 15.2% of targets – the third-best ratio in the league for the position. Fenton's consistency in producing tight coverage should fuel optimism he can ensure Ward's exit is not one that will cause the secondary to struggle.

Fenton has only two interceptions and 18 pass breakups to his name in three seasons. Another year of stingy coverage combined with more on-ball production for a Chiefs team likely to go deep into January again would raise the profile of an under-the-radar but very talented corner.

David Bakhtairi's hopes of being ready for the start of the 2022 season appear in jeopardy after he was placed on the Physically Unable to Perform (PUP) list by the Green Bay Packers.

The Packers open their training camp on Wednesday as they prepare to make another push for a Super Bowl title after suffering more playoff disappointment last season.

But Bakhtiari will not be on the practice field as he continues a prolonged recovery from a torn anterior cruciate ligament and meniscus damage suffered in December 2020.

Players added to the PUP list may be activated at any time before Week 1 but cannot practice before then. 

Five-time All-Pro Bakhtiari played in just one game in 2021, featuring for 27 snaps against the Detroit Lions in Week 18.

However, he was absent as the Packers suffered a 13-10 defeat to the San Francisco 49ers in the Divisional Round of the NFC playoffs.

In 2020, Bakhtiari allowed a pressure rate of just 2.8 per cent, tied for the best in the NFL among left tackles with Andrew Whitworth, per Stats Perform data.

Should he be able unable to line up for the Packers' Week 1 clash with the Minnesota Vikings, Yosh Nijman – who started eight games in 2021 – would likely step into the breach

The final celebration of the Los Angeles Rams' 2021 championship season concluded with Thursday's Super Bowl LVI ring ceremony.

And with that, Sean McVay and the Rams are focused on the season ahead.

The Rams open training camp on Sunday, just over five months after they beat the Cincinnati Bengals 23-20 in the Super Bowl.

"It was kind of good timing, because now it represents, 'Let's turn the page,'" McVay said on Friday. ''Let's not minimise what a great year last year was, but that's not going to have anything to do with this year.''

No team has won back-to-back Super Bowls since the New England Patriots did so in February 2005, and McVay realises there is a reason it has been nearly two decades since it has been accomplished.

''So many things have to go right,'' McVay added. ''We could be a better team this year, and I think we've got a chance to do that, and it might not mean we win a Super Bowl, because there are a lot of things that take place throughout the course of a game - the bounce of a ball here - certain things that are out of your control.''

The Rams had quite a few close calls en route to hoisting the Lombardi Trophy with three-point victories over the Tampa Bay Buccaneers, the San Francisco 49ers and the Bengals in the playoffs.

While there are some parts of the game that coaches and players cannot control, McVay acknowledged that with proper preparation and the right mind-set, the team will be in the best position to win and avoid a dreaded Super Bowl hangover.

''A hangover, to me, what that entails is guys think they're better than they are,'' said McVay, whose Rams missed the playoffs in 2018 after reaching the Super Bowl the previous season.

''They stop working the right way, complacency sets in and the previous success you think is going to have anything to do with your future success. We've got the right kind of guys in our locker room, the right kind of coaches that are intrinsically motivated.''

As the defending champions, the Rams have the honour of kicking off the 2022 season when they host the Buffalo Bills on September 8.

Kyler Murray had no desire to continue his NFL career anywhere other than with the Arizona Cardinals, the quarterback said after signing a five-year, $230.5million contract extension.

Murray and the Cardinals finally reached agreement on a deal that contains $160m guaranteed on Thursday, rewarding him for three seasons of largely stellar play and Arizona's first playoff appearance since 2015 last season.

Negotiations between the two franchises had not always appeared to be harmonious, particularly in late February when Murray and his agent Erik Burkhardt released a statement seemingly urging the Cardinals to prioritise signing the former to a long-term deal rather than simply talking about it.

But, with the saga behind them, Murray is now fully focused on his ultimate goal in the NFL.

"My job is to fulfill my promise and bring a championship here. There's no question about it," Murray said.

"There's no other place that I wanted to be this whole time. And I mean that."

Murray prompted a heated reaction on social media when he deleted all photos relating to the Cardinals from his Instagram account following his appearance in the Pro Bowl.

"All the social media stuff and all that, that's going to happen regardless," Murray added. "Play good, they love you. Play bad, they hate you.

"It is what it is. That's just this day and age. You've got to have tough skin. So, I've grown up in it. So, it's nothing new."

Before being selected as the first overall pick by Arizona in 2019, Murray was picked ninth overall in the 2018 MLB Draft by the Oakland Athletics and signed a contract with the A's.

Asked if this extension ends any prospect of Murray eventually switching to baseball, Cardinals general manager Steve Keim interjected and could not resist a dig at the A's, who have parted with a host of their stars in recent times and have the second-lowest payroll in MLB at $48.5m.

"Did you guys see the payroll of the Oakland A's versus this contract?" Keim replied. "Enough said."
