The Titans added another player to the middle of the offensive line, selecting California center/guard Brian Schwenke in the fourth round of the NFL Draft today. The 6-foot-3, 314-pounder started 36 of 48 games for Cal — 20 at left guard, four at right guard and 12 at center. He was second-team All-American in 2012, per The NFL Report. The Titans drafted Alabama guard Chance Warmack in the first round on Thursday. Earlier this offseason they signed former Bills guard Andy Levitre to a six-year, $46.8 million contract, and added free agents Rob Turner (Rams) and Chris Spencer (Bears).
