There have been new names, new deals, new feuds, old feuds...
Now the 2021 season is on the horizon, but not every situation at the sport's most important position has reached a satisfactory conclusion.
There are intriguing QB scenarios to keep an eye on for plenty of teams this season, as Stats Perform explores.
SAN FRANCISCO 49ERS
Let's start with a rookie. While fellow first-round picks Trevor Lawrence, Zach Wilson and Mac Jones are set for starting roles, Trey Lance has a fight on his hands with the 49ers.
Lance is raw, having played just 19 college games in the FCS, and is set to begin the season behind Jimmy Garoppolo – fit again after becoming one of a remarkable number San Francisco players to suffer with injuries last year, unable to follow up their Super Bowl run.
But Lance's dual-threat ability gives Kyle Shanahan a new dynamic, as evidenced by his 14 rushing touchdowns in 2019 with North Dakota State. Garoppolo has only two career rushing scores.
That is likely to initially put the ball in Lance's hands in the red zone, where his legs should help improve a red zone efficiency of 53.2 per cent from the 2019 season, when a fully fit Niners team ranked 21st in the NFL.
By the end of the year, though, the 21-year-old will undoubtedly be keen for a bigger role, increasing pressure on Garoppolo while the team try to maintain a title challenge.
CHICAGO BEARS
Justin Fields is the second first-round selection starting the year behind an established NFL QB in Andy Dalton.
"There's no need for us to rush Justin," said Bears general manager Ryan Pace last week, explaining they were "very confident" in Dalton. "I just think the more time [Fields] has to learn that and observe, the better off for him," Pace added.
But Fields, who threw for 63 TDs and rushed for a further 15 in two years at Ohio State, is undoubtedly a more realistic long-term solution than Dalton, on his third team in three years.
Fields, like Lance, can run, ranking fifth in the Power 5 among quarterbacks with 7.42 yards per carry last year, but the Bears also need improvement through the air, having ranked 22nd with 228.4 net passing yards per game in 2020.
While the departed Mitchell Trubisky neither threw nor ran the ball well – delivering an accurate, well-thrown ball on just 71.6 per cent of passes and averaging 1.81 yards per carry – Fields (80.18 well-thrown percentage) can do both if given the opportunity.
NEW ORLEANS SAINTS
It is not only the teams who have spent first-round picks on passers who have a battle under center, with the Saints able to consider two options to replace the great Drew Brees.
Jameis Winston threw only 11 passes in New Orleans last season after leaving the Tampa Bay Buccaneers, with the versatile Taysom Hill preferred when Brees was out injured, making four starts at QB.
But Winston has been confirmed as the starter for the new campaign – at least for now. Whether Sean Payton is willing to stick with an entertaining yet erratic QB for a full season remains to be seen.
The 27-year-old became the first player ever to throw 30 TD passes and 30 interceptions in the same NFL season as the Bucs went 7-9 in 2019.
Winston's 10.70 air yards ranked second, yet his pickable pass percentage of 7.69 was second-worst among those with 100 attempts or more.
PHILADELPHIA EAGLES
While some teams have multiple reliable options at QB, the Eagles scarcely have one. Having moved on from Carson Wentz, Jalen Hurts is their starter.
Last time out, in his rookie year, Hurts completed just 52.0 per cent of his passes – the worst rate of any QB with 100 or more attempts – and still could not quite keep up with the league's elite running QBs, averaging 6.00 yards per carry.
Yet Philadelphia's response was to trade out of the number six pick in this year's draft and then opt against taking either Fields or Jones, who remained on the board after they moved back up to 10.
Joe Flacco, now 36, is in as the back-up, while a "fired up" Gardner Minshew has arrived from the Jacksonville Jaguars after 37 TDs in two years but is set for a role as a third-stringer.
Unless Hurts makes significant strides, it is difficult to see how the Eagles will not again be in position to take one of the top college QBs in 2022.
SEATTLE SEAHAWKS
Reigning MVP Aaron Rodgers was at the centre of the most compelling offseason speculation surrounding a quarterback this offseason. However, the Green Bay Packers star was not the only former champion at the centre of offseason speculation this year, with Russell Wilson's agent informing ESPN of four trade destinations that would interest the Seahawks stalwart.
Seattle kept their man in the end, but Wilson will be looking for progress from last season, when he complained of "getting hit too much" – "a pretty normal reaction," according to coach Pete Carroll.
Wilson was in the MVP conversation for the first half of the year but was soon left exposed behind a poor offensive line, sacked 47 times to swell his career total to 394 – the most of any QB since he entered the league.
Although left tackle Duane Brown has missed practice as he waits on a contract extension – another development that has frustrated Wilson – the Seahawks have at least traded for guard Gabe Jackson. That move needs to work.
Wilson last year averaged 8.70 air yards while throwing a pickable pass at the sixth-lowest ratio in the NFL (2.64%), but he has to have help if Seattle are to succeed.
