Dude has kept quiet for the most part and played nice even after Indy has dangled out in the trade market for years now, so I don't necessarily blame him for being fed up and being more vocal about wanting out. They should have moved him years ago granted last year he got injured at the trade deadline.
With that being said, he's not as good as he thinks he is as dude lacks the motor and consistency to be that dude. Sometimes you see it in flashes and other times he's literally just out there on the floor. He's literally the Caris Levert of big men.
