Start Felix Jones or Ryan Grant?

[steeldeeznutz]

I've got 2 RB spots to fill in a PPR league. I have Chris Johnson v NYJ, Ryan Grant v STL, and Felix Jones v CAR. I feel like I can't sit Johnson even if he is playing the best defense of the three. I will definitely start Grant if Marion Barber ends up playing on Monday night so my question is: if Barber doesn't play or they announce he will get very limited touches, do I start Jones over Grant? OR for you real radicals do I start them both over C Johnson?

Def should play grant vs. STL. Pack should be in a position to run.

Grant, GB will have to kill off some time after they run up a big lead and Grant should get a score or two.
