Is the Need for a RB overblown? How about the need for an Edge? The Need for a WR? A CB?
The answer to all of those, I believe, is yes. We aren't drafting a player at 54 because we need him in the sense that we don't have anyone else to play that spot. We're drafting for supplement, and competition.
So to answer your question, I think we could use/get a return of value on a big nickel as much as we could just about any other position in this draft. We're in a good spot, we can be luxurious and take whose there.
