Quarterbacks currently on the roster: Jameis Winston, Mike Glennon, Ryan Griffin, Dan LeFevour
The Tampa Bay Buccaneers Jameis Winston number one overall last year, and he was pretty much all they could hope for. Winston made the Pro Bowl as a rookie, played well after an ugly first game, and looks like a future franchise quarterback. While he had his faults, those faults are normal for a rookie -- and he should be much-improved in his second season. Offseason reports that he's transformed his body hint at that, and no one's ever had any legitimate complaints about his work ethic. The future looks bright for Winston.
Meanwhile, Tampa Bay has Mike Glennon wilting on the bench. Glennon hasn't exactly been a dominant quarterback, but he has looked like a competent player when he's started -- a low-level starter, or a top-level backup. The kind of guy that teams sign every offseason in the hope that he can be more than just a backup. The Bucs have been preparing for his departure for a year, by keeping Ryan Griffin on the 53-man roster as an inactive throughout the 2015 season, by recently signing Dan LeFevour and by openly admitting to talking with several teams about trading him. Glennon is a free agent next year and Jason Licht wants to get something in return for him.
Such a trade may have to wait until draft day, if it comes at all. If they trade him, they've prepared by inviting several late-round quarterback prospects in for workouts, meetings and more so they have competition for Griffin, currently Glennon's heir apparent. A mid- to late-round pick on a quarterback seems likely, assuming the Bucs can find a way to trade Glennon for a significant enough reward. Otherwise, they'll go into the season with a quality backup quarterback - there's worse things in the world.
