Because KG didn't hit anyone above the shoulder.
PS: I'm not saying that Malone should have been suspended... I think it was a gay, really hard shoulder that was not the same as KG's except that it was a PF using a Shoulder. That's where the similarity ends.
Either way, it happens, and I'm more concerned with KG getting hacked out there. It wears him down, and he's not a big fatass like Shaq who can handle the abuse
. He's halfway between Shaq and AI... and we all know AI will be forced to retire soon from all his injuries.
