Overrated? Absolutely.. Every time I see WM take a handoff.. I'm reminded more and more of Eddie George and Eric Dickerson.. mind you, not the young versions of these RB's, but the aging, dance behind the line, run upright, won't hit the line hard versions.
As far as what we could get for him.. Probably not as much as most people would think.. I think you get a late 2nd for him as best. Teams are learning more and more that a premier RB is not a neccesity in todays NFL.. you can be just as successful with a couple of so-so RB's behind a strong O'line. Teams that spend on RB's first, are nuts. (Read: Cardinals, Raiders)
Personally, I thought we cut the best RB we had in Training Camp.
