3 PPR RB? Peterson, DMC, Spiller, Ridley

[manicottimafioso]

10-team PPR league w/standard scoring + punt/kick return yardage. I need to start 2 RBs and a FLEX this week from the following:
- Adrian Peterson vs. SF
- Darren McFadden vs. PIT
- CJ Spiller vs. CLE
- Stevan Ridley vs. BAL

OK, I'm going with Spiller and McFadden.

Peterson or Ridley? I'm leaning towards Ridley based on matchups, but Vereen may steal some carries.
