I agree, but I think we still have to load up on running backs. If my above post is anywhere close to reality, that's still a lot of carries from non-running backs...although with Riddick being a former RB and Atkinson kind of being in the same mold, it might not seem as bad.
Not that there's a huge problem with that, God knows Holtz platooned the crap out of many of his teams and their runners.
But we have 6,389 linemen on both sides of the ball now and ridiculous depth there. We should be able to boost the depth at RB. And I think we will eventually.
