Kurt Warner, Arizona Cardinals
Warner led a second team to the Super Bowl, his third trip to the big game, and put up impressive numbers with his desert-based passing attack. He may weigh his options but remaining in Arizona would seem to be in the cards.
Kerry Collins, Tennessee Titans
Like Warner, Collins has been to the big game and has led different teams to conference championships. He showed last year that he can still play at a high level.
Jeff Garcia, Tampa Bay BuccaneersAnother aging veteran who's been a proven winner wherever he's been. Garcia might have more years left to play than the aforementioned QBs, which could factor into where he winds up in '09.
Matt Cassel, New England Patriots
The player with the biggest question mark is, of course, Cassel, whose future is tied to both the Pats franchise tag and Tom Brady's health. It's possible that New England could hold onto the backup-turned-star. That would book the team for some $29 million on the cap for two quarterbacks. More likely is a trade scenario. In that case New England could be looking for added depth in free agency.
Ryan Fitzpatrick, Cincinnati Bengals
The Harvard grad proved he could be a starting quarterback in the NFL, albeit with the lowly Bengals. He's an underrated playmaker who could be a quality backup on a good team, or perhaps continue to start (and develop) on a lesser team.
Luke McCown, Tampa Bay BuccaneersThe athletic McCown can make plays with his arm and his legs. If Cassel is moved, McCown might be an option to backup Brady.
