Because he has an incredible amount of potential and is quite possibly one of the most athletic centers you will likely see.
Blocking 10 shots is not "not giving a fuck" in a game where you are losing by that many.
Yes he does some stupid shit but what do you expect when he is playing in Washington, a team and organization that is collectively retarded? Dumb breeds dumb so Washington wasn't a good place for him to land.
Send him to someone like Hakeem Olajuwon for a period of time, get his head straight and you would see one of the best centers you are ever likely to see in the modern version of the game. That's why he got drafted!
The sooner he gets out of Washington and into an organization that can funnel that potential the better off he will be.
