At that point, the starting PF could be back in play and i wouldn't have any idea how that will be settled.
i would guess that Davis wins all ties as far as starting is concerned while Childs and Dastrup improvements increasingly demand more minutes. Moreover, Kaufusi joins the mix at that point and he will almost certainly serve as Eric's back up.
That Childs and/or Dastrup may fill in at SF is believed to be a consideration right now. Whether or not that plays out might depend on the freshmen bigs' ability to hit the 3 and defend at that spot. Another consideration would be Guinn's or Beo's demonstrated value at the wing. In any case, Bryant, Emery, Haws, and Rose cannot man 3 positions without additional support.
