Someone said C-Dub is a run first kind of coach, but actually that's not exactly true. He ran more than he passed this year, but that's the first time that's happened in his offense since he's been OC, and it was only b/c of the presence of Correy Dillon. In the past, his offenses have thrown much more than ran. I think he makes his offense around what he's got to work with. Walker is a solid back (he did set ND's freshman rushing record...). He might not be a pound it up the middle, 27-30 carry per game back, but that's ok, b/c Quinn should be able to take the pressure off if he's coached right. I don't see why Walker can't carry the ball 20 times a game though & still get 90-100 yards per game, w/ quinn passing the rest of the time.
In short, an extra RB would be nice, but there are A LOT more pressing needs in South Bend right now to me.
