FILE -- In this Aug. 8, 2013 file photo, Tennessee Titans running back Shonn Greene (23) carries the ball against the Washington Redskins in the first quarter of a preseason NFL football game in Nashville, Tenn. Titans head coach Mike Munchak wants to be able to run the ball when he wants to and when he needs to. The Tennessee Titans gave a glimpse that their revamped offensive line combined with Greene and Chris Johnson might be up to doing just that in their preseason opener. (AP Photo/Mark Zaleski, File)
