After parting with running back Chris Johnson last month, the Titans have made no secret of the fact they're looking for more help at the position. How early they take pick a running back in the NFL draft this weekend is the big question. "I think running back-wise, I have been pretty open at saying that is something we have to look at taking at some point,'' general manager Ruston Webster said on Tuesday. "I would probably go there." Shonn Greene is currently in line to replace Johnson as the starter. In his first season with the Titans last year he rushed for just 295 yards on 77 carries, although he missed five games because of a knee injury. Veterans Leon Washington and Jackie Battle also return, and free agent running back/wide receiver Dexter McCluster was signed. The Titans plan to give McCluster more snaps at running back than he got with the Chiefs, his team for the past four seasons.
