Need help picking 3 RBs

Full point PPR.
2 RBs 1 flex

RBs are McCaffrey, Michel, Breida, J.Jacobs, D. Thompson, McCoy

Need to start 2 and 1 in flex contemplating going D Thompson in flex for potential that McCoy may not play much but with all those other RBs I’m having a tough time.

CMC, Michel and Breida for sure
