If you put it all into one deal... so Bojan to NY, Knox to OKC, Utah gets 19, 32, and Williams from OKC... then the trade exception gets bigger and could be pretty useful. I hope if we pinch pennis on Bogey we don't give up value to drop Favs too. You'd have an 18.7M trade exception to play around with. You can wait until people see they need a center after FA and make maybe a better move to drop Favs... then you could hunt at the trade deadline with a big trade exception to make any kind of deal work. Most likely it goes unused but you have the ability to make a medium sized deal if something good comes up.
A lot of folks wouldn't want to hear it here... but you could also match a reasonable offer on Niang (under 5M) if you wanted to.
