The Tampa Bay Buccaneers currently have 75 players on their 2018 roster, 15 of whom will become unrestricted free agents if they don't re-sign with the team before March 14. Some of those players have more obviously defined roles for the season ahead; Gerald McCoy will be anchoring the defensive line, for instance, while Jameis Winston will still be directing the offense. Others will spend the months ahead trying to clarify their roles; it's not clear who will be the primary ballcarrier in the backfield, for example.
No matter how secure their spots in the lineup are or are not, however, every player on the roster faces some uncertainty in 2018.
