Eugene Amano, OG
This could be the unheralded steal of the free agency market, presuming the Titans do not extend the 6-3, 310-pounder. Although veteran Kevin Mawae was the headliner on Chris Johnson's offensive line and will be on most free agent lists, he doesn't make this one. Amano does. He is consistent and still just 27 in his sixth NFL season. He is a natural center, too, so his versatility could fit any number of teams. Amano has been the regular starter at left guard for the Titans the past two seasons.
