Im sorry, but I cant be positive about this at all and its mostly because there is no plan.
Yeah I don't like the move because it reminds me of the old Wiz. Pre-Gilbert. Okafor is just an overpaid stiff like Ike Austin. Ariza has talent but has never in his life been an impact player.
This move alone is a zero, I hope it doesn't hurt too much capwise. The only thing that matters is whether or not John Wall can play with them...
