He deliberately provoked Rockets fans(and Houstonians in general) on his way out the door. That's entirely on him. His alienating of the Mavs and Grizzlies fanbases are less his fault since that's mostly due to injury. To be honest, if I'm a Memphis fan, I'd be a lot angrier at management. Two straight seasons end due to injury. He had microfracture surgery in 2015. And they hand him a contract like that?!
