Here is another reason why I think the Raptors have to trade Rudy.
Bulls need cap space to sign Mirotic. This summer, he no longer qualifies for his rookie deal. Bulls can only sign him with cap space.
Keeping Boozer, Bulls have no cap space. If they are a tax team next year they hit the repeater tax.
If Raptors trade Gay to, say Charlotte, for Gordon (expiring) and 1 first round pick, on draft night they could acquire Boozer straight up with no salary going back. So the question becomes would Chicago trade Charlotte's pick (and lets get greedy, their own 2014 or 2015 pick) for $16.8M in cap space? Of course they can do that with the amnesty clause as well, so maybe a better question is: are giving up picks worth $16.8M?
