You are Steelers GM.
You're team is set in stone except for one roster spot. Neither of these two players would start on the roster you currently have (set in stone.) It doesn't matter at this point who is at WR or RB...you're in "good" shape...trust yourself...you're the Steelers GM. This last spot is a luxury spot.
Do you take Rashard Mendenhall and his injury which may not let him see the field in 2012 and off the field "issues?"
or
An aging Hines Ward with little left in the tank?
