I just got offered Newton, Sproles, and Mike Williams (TB) for DMC. I'm weak in all 3 positions after losing A. Johnson and Mendenhall. However, DMC has been the sole bright spot on my team... Am I giving up too much? The guy offering this also has M. Austin, R. Wayne, S. Smith (CAR) for WR, which is what I need most, and J. Best and R. Matthews for RBs. Thoughts?
