A month on from the Tampa Bay Buccaneers' triumph in Super Bowl LV, teams across the NFL are preparing to make moves they hope will propel them towards glory.

This year's free agency period is unlikely to see a move as decisive as Tom Brady's decision to swap the New England Patriots for the Buccaneers.

However, with franchises dealing with a likely declining salary cap because of the impact of playing a season largely without fans, the chaos of the league's open market should still be fascinating to watch.

But which teams will be the most active when the NFL opens the window for teams to begin negotiating with free agents next Monday?

Here we look at those likeliest to be busy and the signings they could make.

Jacksonville Jaguars

Cap Space: $85.7million

From having the number one pick in the draft, which they will almost certainly use on Clemson quarterback Trevor Lawrence, to having the most salary cap space in the league, the Jaguars are the franchise that holds the keys to the offseason.

New general manager Trent Baalke and first-time NFL head coach Urban Meyer have no shortage of needs to address following a one-win 2020 season.

Lawrence will require much-improved pass protection if he is to thrive and lead Jacksonville to contention. With that in mind, they should be in on the sweepstakes for All-Pro left tackle Trent Williams, who cannot be franchise-tagged by the San Francisco 49ers and is likely to command over $20m a year.

Given the money at their disposal, the Jags will be among the leading candidates to lure edge rusher Shaquil Barrett from the Buccaneers. He could form a formidable tandem with Jacksonville's 2019 first-round pick Josh Allen.

New York Jets

Cap Space: $72.4million

The Jets' offseason will be defined by whether they stick with Sam Darnold at quarterback or use their second overall pick to select one of the top four signal-callers in the draft class.

But beyond that pivotal decision, Jets GM Joe Douglas and Robert Saleh have an arduous task of turning one of the worst rosters in football into one primed to contend in the AFC.

Saleh may look to his old team, the 49ers, for whom he was defensive coordinator from 2017 to 2020, to build up his secondary in New York.

Richard Sherman could be tempted cross country to stay with Saleh, while slot cornerback K'Waun Williams is a New Jersey native who could offer the Jets a dependable presence familiar with the defense.

New England Patriots

Cap Space: $72.6million

Bill Belichick has rarely been one to spend big in his storied tenure as head coach and de-facto GM of the Patriots.

However, possessing a talent-poor roster and in danger of being left behind in the AFC East, this could be the year where he changes course, and Belichick has already made a significant move, bringing back offensive tackle Trent Brown in a trade with the Las Vegas Raiders.

New England must make a decision at quarterback after an unconvincing season from Cam Newton as Tom Brady's successor.

Regardless of who is under center, the Patriots will not compete if their quarterback does not have dynamic weapons among their pass-catchers.

Belichick has typically had a blindspot for wide receivers in the draft, so more experienced options with playmaking upside like Corey Davis and Marvin Jones could find a home in New England. Hunter Henry may also be a target if the Los Angeles Chargers decide not to pay the tight end who was franchise-tagged last year.

Indianapolis Colts

Cap Space: $50.5million

The Colts have the man they hope will be the answer at quarterback following Philip Rivers' retirement, backing Carson Wentz to rehabilitate his career under Frank Reich and acquiring him from the Philadelphia Eagles.

In terms of a support system, Wentz is heading into a team with a strong one in place, yet it could still be improved and the Colts have the wiggle room to be aggressive.

They may be an attractive destination for the aforementioned Williams, who would be an upgrade on the retired Anthony Castonzo at left tackle.

Veteran wide receiver T.Y. Hilton could leave in free agency and it would not be wise for the Colts to rely too heavily on Michael Pittman Jr at wideout despite a strong end to his rookie season.

As they look to maximise Wentz's chances of being successful, a move for a high-profile receiver like Allen Robinson could make a great deal of sense for a team looking to challenge the Kansas City Chiefs in the AFC.

Tampa Bay Buccaneers

Cap Space: $18.1million

The outlier here in terms of cap space but, having blown out the Chiefs in Super Bowl LV, the Buccaneers will surely not be short of players wanting to join them on short-term deals to link up with Brady and make another push for a Lombardi Trophy.

Tampa will be busy enough trying to hold on to as many in-house free agents as possible, but the Bucs will find intriguing potential temporary options in areas of need on the open market.

Reinforcements may well be required on the defensive line given the possibility of Barrett going elsewhere.

The Bucs have seen one veteran, Jason Pierre-Paul, thrive on the edge. Perhaps Justin Houston, who has 19 sacks over his last two seasons with the Colts, could be tempted by the chance to chase a ring in Tampa.

On the interior, the Buccaneers have a monstrous presence in Vita Vea, and their strength in that area could allow them to take a swing on a former first-rounder in Sheldon Rankins, who has seen his career with the New Orleans Saints stall because of injuries but had eight sacks back in 2018.
