ALLEN PARK -- After spending the offseason plowing cash and draft picks into their running game, the Lions still aren't done.
Detroit has agreed to terms with running back Donnel Pumphrey according to NFL Network. That comes on the heels of other additions like running backs LeGarrette Blount (free agency) and Kerryon Johnson (draft), plus a new offensive lineman in first-round pick Frank Ragnow and even a new offensive line coach in Jeff Davidson.
Now the big question is what happens next.
The Lions already have four running backs on the roster in Johnson, Blount, Theo Riddick and Ameer Abdulla.
