Lots of coverage lately about the unhinged behavior of Kevin Garnett. Of course you've seen the much discussed incidents with Jose Calderon and Jerryd Bayless. Many pundits consider his antics a motivational tactic. I'm more inclined to think that KG's just a foul-mouthed spaz with a glandular disorder or some particularly obscene form of Tourette's Syndrome.
He's certainly no tough guy. Despite all the trashtalk, this is what happens when somebody actually calls KG out (in this case former journeyman Anthony Peeler).
Personally, I've always been entertained by his quirkiness but I'm surprised that more players haven't pulled a Peeler and clocked his ass.
