I agree we need more depth at those positions, but if you think about what they want to do with Coffee, RB becomes a much larger need. They want a 2 back system. Hopefully Coffee will play every week this year.
A second RB isn't a luxury anymore. RBs take too many hits to handle the load themselves. Gore will break down in our new offense if we don't pickup Coffee or Brown in the 3rd. I think you would be hardpressed to find many teams with worse backup RBs than us before this draft.
