The upcoming NFL free agency period is shaping up to be a critical time for several teams, especially those facing salary cap constraints. The New Orleans Saints, for instance, are significantly over the cap and may need to release quarterback Derek Carr to free up $30 million. This comes as they seek to address numerous roster gaps, including receiver and secondary help.

Meanwhile, the Buffalo Bills are a mere $8 million over the cap, and restructuring Josh Allen's contract could provide much-needed relief. They also aim to explore options at wide receiver and defensive positions after last season's shortcomings.

Teams like the Atlanta Falcons and Kansas City Chiefs are contemplating significant roster adjustments as well, with potential trades and restructures on the horizon. The Chiefs, for example, could minimize their cap hit by extending key players and exploring new offensive line dynamics. The Tampa Bay Buccaneers, despite having some cap space, are looking at restructures to bolster their offensive line and pass-rush depth ahead of free agency.
