Each year, every franchise has to make tough decisions regarding which players to keep on their roster and which free agents to target.
Sometimes, players are cut because they either aren't good enough or don't fit a team's scheme (think Donovan McNabb in DC: a good player, but not right for Shanahan's scheme).
Other times, players are let go or not re-signed, not because they aren't good, but because they cost too much towards a team's salary cap.
Though we don't know what will come of the current NFL owners and players discussions, what we do know is that there will be a salary cap. There is also a possibility it could be a bit stricter than in the past (or not; we're still fuzzy on those details).
I present to you a list of players who could find themselves traded or released due to the salary cap.
