I'd rank them:
Brown- will be seeing more carries after last weeks performance and Indy should get up big early so they will try and run out the clock
Rice- healthy and a solid RB
Barber- probable to play but its already been announced that choice will get a majority of the carries with his performance last week and barber's healthy
Smith- I doubt he will play and its a game time decision so its not worth the risk. Plus if he does it will only be a few touches. He was limited in his first practice back on thursday and is going against a good Bears defense.
