Based on what I've been seeing, Sampson, Carter, DJ, combo of Nolen/Devoe/Westbrook. Although I must say I'm less than impressed with the guard play against better competition. It makes us a little small but they have the best chance of gelling against a top team.
An eleven man rotation is great to get you to the dance, but eventually it'll come down to 5 on 5. That scares me.
