What's cut & dry is that someone got seven stitches and broke a tooth and someone else didn't.
I don't care what was said or what else was going on, there's no justification for that kind of garbage, especially during an offseason workout. But don't worry, the T-Mutts won't have the balls to so much as reprimand Garnett.
People call hockey players thugs and goons for this kind of behavior, Kevin Garnett does it (to a teammate no less) and it's no big deal. Whatever.
