Yea, not to disagree with any of the higher ups, but there is a HUGE difference between being an arm chair warrior, and to know when someone is fucking up the rubber guard. BJ hasn't hugged the knee since the first time I saw him use it. Don't get me wrong: I love the hell out of Penn. He is a GOD of grappling in MMA, and has sick jits, great hands, the whole 9 yards so to speak, but his rubber guard is, in fact, horrible. Dude does NOT hug the knee like he should. I'm not trying to take anything away from the man, but OP is right. You don't need to be a black belt in 10th Planet JJ to know that if you don't hug the knee tight, that the rubber guard falls apart. He has a great game, but the rubber guard isn't part of it at the moment. If he wants to rock it in MMA, more power to him, but he needs to put in more time with it and work out its kinks.
