Locker isn't going to just sit on the bench for three years and then happily re-sign with the Titans. I think there's a very good chance that a Manning signing means the (eventual) end of Locker in Tennessee. If the Titans truly believe that Locker is a franchise QB, then it makes the decision a crucial one. Locker is ready to start in the NFL now and he surely knows that. He might be willing to sit quietly on the bench for a year, but he will eventually want out. And he would be justified. A highly-drafted quarterback's second contract is where he makes his money. Locker will want to be starting for a team before his 4-year deal expires. Frankly, a #8 overall pick needs to be starting within a year or two. I am just not convinced that a few years of potentially contending with Manning is worth losing an entire career of a player as promising as Locker.
