Titans quarterback Charlie Whitehurst was signed this year not only to back up starter Jake Locker, but also to help teach Locker the offensive system of new coach Ken Whisenhunt, whom Whitehurst played for last year in San Diego. Whitehurst thinks Locker is going to look great in this offense. Whitehurst told the Tennessean that he expects Locker to look better than he has before. “Part of my job this year is to help guys in the new offense,” Whitehurst said. “At the backup quarterback spot, you have to be ready to play if called upon and that is my first priority. I have been doing my best to help Jake and he has helped me in this process. We’re helping each other. I think he is primed to have a heck of a season, and if need be, I’ll be ready to play.” This is a make-or-break season for Locker, who is heading into the final season of his contract. If he looks as good as Whisenhunt thinks he will, Locker will get a lucrative contract in Tennessee or somewhere else next year. If not, this may be the last time Locker enters a season as an NFL starter.
