I think that the Steelers should go with 2 RBs in the backfield against the league's 21st ranked rush defense this week...
Skill positions in the base offense would be:
Sanders (or Cotchery, depending)
Both guys can run...I've not seen much of Dwyer in pass pro, but Redman is certainly capable...both guys can catch passes out of the backfield as a safety valve...
Just my opinion...
