Re: Let's just stick with Mendenhall.
Keep him for cheap. Someone mentioned earlier a better zone blocking scheme and the improved O-line talent should hopefully help open some holes on the front lines. A backfield of Mendy, Dwyer, Redman doesn't sound half bad to me. I'd prefer to get a Ryan Mathews like guy out of the draft then run with the 3 above, and I really wish I could include Rainey on the list, curse his damn stupidity.
Mendy is the best option currently on the roster, and I hope the Steelers decide to keep him for cheap and let him avenge his fumble in the Green Bay SuperBowl.
