Right, that's what he says, because he never gives a straight answer if he doesn't have to. He also says he cuts off the sleeves because his "arms are too short." I don't even have to post a link, just google it, plenty of stories are out there about it.
He'd rather wear a suit and tie than be forced to wear Nike gear, and he likes to f*#% with the media. Don't get me wrong, I can't stand the guy, but I like the cut of his jib sometimes. SOMETIMES.
