Ummmm that makes no sense...
Why amnesty him (you still owe him his money and have to pay him his money) when you can get an expiring contract and actually save money.
While the trade may limit Zeller at first, in the long run it would help because he would get to learn from Boozer for the remainder of this year and next year then the Cats could let Boozer walk in free agency and let Zeller take over.
By the way... the Bulls are most likely getting that pick this year anyway.
As for trading Gordon for Pau... talks would not get far because we would have to add a contract for the salaries to match and I guarantee they would ask for MKG.
Have to tell that to all the sites talking about it. Either Grantland or ESPN is where I read it today, also saw it on Sporting News. Quick Google search shows ESPN and others reporting the rumor and Boozer even talking about it.
And yes they'd still have to pay him, but only some of that contract. Not all of it.
