What 2rbs to start? Forte vs Wash, Bradshaw vs Dal, Hilis vs NO or Mendenhall vs Mia?

The Dolphins are the toughest of the run Ds these guys face this week, but I would play Mendenhall anyway. He's the #5 RB right now (pts/game; standard Yahoo scoring) and has played well against everyone. Bradshaw has a tough match up on the road against Dallas who have played well against RBs like Peterson. Between Hillis and Forte I would go with Hillis. The Saints allow more fantasy points to RBs than the others and have allowed twice as many RB TDs as the Redskins and Dolphins.
