Week 11 RB: Matt Forte or Ronnie Brown?

I'm already playing Westbrook as RB. For slot 2, need to decide between Matt Forte (vs Green Bay) or Ronnie Brown (vs Oakland). Yahoo Projections favor Brown 18 FP to Forte's 14 FP. However, all the experts favors Forte over Brown. Go with Forte? (I also have Slaton and Jamal Lewis to choose from.) Thanks!
