I don't see what all the speculation is for, the Lions have invested in both Keiland Williams ( from Washington, on the squad for a year now) and Joique Bell ( on the squad for 8 months from various practice squads) This same kind of banter happened when Brady went down. Cassel was the backup for a reason. They invested in Cassel and sunk the cost of his training, coaching and roster spot and salary cap hold for a reason. Maybe the Lions are going to look for injury depth, but they are going to see what they have on the roster first. Look at Arian Foster, came from nowhere. Not saying these guys will be the next Terrell Davis or Arian Foster, but am saying running back has such low positional value in the NFL, both the draft and free agency for a reason. You can mine a serviceable back from all kinds of sources. For better or worse, Leshoure, Bell and Williams already are entrenched in the system, in the routine, know the coaches, the coaches know what they can and can't do and any guy they could find, and especially cheap, he's CHEAP AND AVAILABLE FOR A REASON. If Mayhew has shown anything, it's that he has a high valuation of draft picks and assets in general, just like most GMs and just like most GMs given this new CBA. The Lions have plenty of holes elsewhere to spend money and draft picks for the future. Let's see what the kids they have can do first.
