The Tampa Bay Buccaneers are going to cut Anthony Collins. They'll cut him before Wednesday, March 12, which is when his full 2015 salary becomes guaranteed. Cutting him before then will save the Bucs $3 million, and that's exactly what they want.
The Bucs made it clear they'll cut Collins when they deactivated him for the team's final three games of the season. They made that even more obvious when they started shopping him to other teams, which is what NFL Network's Ian Rapoport says they did. I wish them good luck, but they'll find no takers. Whoever wants a backup lineman won't be willing to pay him $6 million for his services this year.
The Bucs having to say goodbye to Collins is both bad and good. It's bad, because it means he's a free agency bust who they paid $9 million to be a largely useless player. It's good because they structured his contract to be able to say goodbye without too much damage, and they'll be able to find a better replacement for him this offseason.
