With 2 spots open, I would go for Joe Smith and Bobby Jackson. Both are good defenders, and it gives us veteran depth at both positions. With Pruitt's inconsistency, Jackson could take over as backup PG so House can continue to spot up for 3's, and Smith could pick up the slack of inconsistent Powe and BBD. When KG is back our lineup would be.
Rondo - Jackson
Ray - House
Pierce - Tony
KG - Joe - Powe
Perk - Scal - BBD
Pruitt, Walker, and Giddens can all go back inactive so we can defend a title.
