Running backs to start?

Portis didn't play much last week and he was healthy enough to practice Wednesday. I think he is ready to go. I really think he could get a ton if he is on at all. Jackson has a decent matchup and came through last week in good shape. Grant had a decent week and his thumb wasn't hurting him, and has a decent matchup too. Right about Slaton and Parker. I would try Portis and Grant. Slaton might be shut down but maybe not. FWIW I have Portis too but I will be starting Pierre Thomas and have to decide between Portis and LenDale White.
