The Tampa Bay Buccaneers are "open to listening to offers" when it comes to center/guard Jeremy Zuttah, according to Jason La Canfora. He also noted that the Bucs would keep Zuttah if they could not find good compensation in a trade.
Zuttah is set to carry a non-guaranteed $4.5 million salary and cap figure this season, which is somewhat more than his play warrants. However, he's a better player than any available free agent, and his ability to play all three interior offensive line positions gives him a lot of added value.
The fact that the Bucs are open to trading Zuttah should be no real surprise: they'd be open to trading any player, at the right price. The question is whether any other team would be willing to trade for Zuttah given his cap figure, and how much they'd be willing to give up for a decent, versatile but hardly great interior lineman.
The Bucs are probably better off keeping Zuttah on the roster. While they've signed Evan Dietrich-Smith and Jamon Meredith, they still lack depth and quality across the offensive line. Carl Nicks' participation this year (or any year) is still in doubt due to his foot injury, while starting Meredith or Oniel Cousins would not be a very productive plan.
If the Bucs were to trade Zuttah, they'd almost be forced to use one of their top three draft picks on an (interior) offensive lineman. That may be a good idea anyway, but it's never good to be pigeon-holed into a draft pick, especially after the team has gone to great lengths to fill all of their needs in free agency anyway.
