This kind of stuff used to be commonplace in the NBA. One time Rudy T (by his own account) was having trouble with Wilt Chamberlain. Rudy was just a rookie or 2nd year player. He grabbed Wilt's shorts right before Wilt went for a rebound and basically pantsed the Stilt in front of an entire stadium. There was no fine, but there a threat of violence from Chamberlain. The whole thing just seems kind of silly.
TNT just showed replays of JR Smith untying opponents shoe laces when they are lined up for free throw rebounding. Man, that should be a technical and automatic fine. What a punk thing to do. Barkley would punch him if he tried that on him.
