should i trade jamaal charles for rashard mendenhall in a full ppr. My initial plan was to draft rashard but he went right before i picked JC. My thought is with the loss of short yardage duties he could be had probably. I know the coach has said rashard is fine at the goal line but has trouble converting 3rd and short type runs because he runs to break one instead of running for a first so my feeling is this wont effect his goal line production. Thoughts?
