Which 2 out of 3 of these Running Backs should I start this sunday? Matt Forte, Kevin Smith or LeSean McCoy?

I have a choice finally this week, not that it is a spectacular one, but a choice non the less. I need to start two out of these three RB's this sunday, which should I start? Matt Forte(CHI) vs. CLE, or Kevin Smith(DET) vs. STL, or LeSean McCoy(PHI) vs. NYG. ALL of these guys are gonna get all the carries, mccoy as well since westbrook is out this sunday, with that said..I ume my best options would be Forte and Smith but when McCoy took over for westbrook a few weeks ago, he had a very nice outing. So please a little advice, would be nice! thnx.
