Will Titans target RB depth in draft?

With Chris Johnson gone and coach Ken Whisenhunt in, the Tennessee Titans are going to have a new look to their backfield in 2014. Whisenhunt has said that he intends to use Dexter McCluster, Shonn Greene, Leon Washington and Jackie Battle in some form of a running back by committee. However, he also said the Titans could add another running back via the draft.
