Locker's job in jeopardy?

Acknowledging that they hadn't done a satisfactory job of finding and developing interior O-line talent over the past few seasons, the Tennessee Titans struck early and often in free agency and the draft in securing players to beef up that part of the roster. As a result, there could be three new faces in those positions in the starting lineup by Week 1: FA signing Andy Levitre and first-round pick Chance Warmack are almost certain shoo-ins at LG and RG, respectively, and some believe that Brian Schwenke should be the man at center. All of this was done in part to help Chris Johnson re-establish himself as a top-flight RB, but it should also benefit Jake Locker as he attempts to prove that he can be a franchise QB. Some believe that his job is already in jeopardy as the start of camp awaits.
