Who will back up Jake Locker?

New Tennessee Titans coach Ken Whisenhunt is slated to have Jake Locker as his starting quarterback. That decision was cemented when the Titans released Ryan Fitzpatrick. Say what you want about Fitzpatrick's skills, but he had plenty of experience, having played in 84 games as a pro. The same cannot be said for the players they added to the roster to replace Fitzpatrick.
