If JO and Shaq both come back will be a problem to find minutes to bring a young big along, would not mind bringing Kristic and Semih back. Semih can cover alot of ground and disrupts a lot of shot around the rim.
Semih's not walking through that door. Cleveland's keeping him around.
If the C's go big with their pick and that player doesn't see court time, it would be because Shaq and JO took all the minutes. Shaq's toast, JO is an injury waiting to happen and Krstic won't be enough (a suitable backup certainly, but not the guy you want starting at center to contend).
Any new player will sit because at #25 in a weak draft, the kid has limitations and Doc doesn't play rookies unless he's out of live bodies (and even then Doc will run the starters into the ground).
