Noah is still on the hook for the Knicks. He's reportedly refusing to give up some of the money in the buyout. So ergo, he's still with the Knicks to this date. If you haven't watched his recent video with his blond beard on his exile. Then you would know the Knicks clearly aren't going to bring him back.
Horford is still high on Noah, so if he gets waived/bought out, I could see him coming here, and having a decent impact like Baynes in sparse 7-10 minutes.
