If you look under the basket you see Danny Ainge throwing a towel in the air trying to distract JJ Hickson of the Cavs. A lot of people say this is poor judgment and gay, I believe this is awesome. Other than Mark Cuban you would never see any other higher up act this way, it means they really care about the team. There is nothing in the rule book that says you can't do it, so why not?
Ainge is the man, the Cavs are gay.
