That's a checkmate. I find it very unfair and i'm a Cavs fan. Probably, he really can't let himself trusting Dan Gilbert. If he wanna do the symbol forever, he'll stay If he wanna continue winning, chasin' Micheal, he has to go. Cleveland is out of gas with solutions to reach the title. However they throw the pick, they'll lost, just like Kyrie's trade. Not because their FO is bad (on the contrary, i had so much love&respect for Griff and the same is for Koby Alt), but when you desperately need an upgrade and all the others franchises know it, don't believe they won't use it against you in any form. So he has to be clear, allowing the Cavs org to make some lock-up moves.
EDIT: Can he sign a S&T to go away?
