The first thing I thought: Rasheed and Scally are good friends?! LOL
Secondly, I hope he comes back to the Celtics. If he went to Chicago he'd fit right in there and could create some problems in the playoffs.
With J.O.'s health in question and Shaq always capable of getting hurt, he'd be quality depth that is familiar with the system and players.
If we got 'sheed back I'd say the pecking order for centers would be:
Shaq, Perkins, Rasheed, Davis, Jermaine, Semih.
