Backup: Mike Glennon

Best-case scenario: With a strong offense featuring Doug Martin and Vincent Jackson, Josh Freeman realizes his potential and leads the Buccaneers deep into the playoffs. How far? If Freeman is playing well, the NFC Championship is a strong possibility.
Worst-case scenario: It's hard to believe that the Buccaneers didn't draft Mike Glennon with the intent to: 1) light a fire up Josh Freeman's ass, 2) have a back-up plan in place if Freeman doesn't get his act together this season. Simply put, if Freeman struggles again, Glennon will be the team's starting quarterback. And it won't take an entire season to reach that conclusion.
