Why won't even move up and fight Anderson Silva...? :shrug: If he really wants to prove he is the best pound for pound fighter in the world why doesn't he have the balls to move up ONE weight class. Anderson didn't have a problem when he moved up, BJ Penn had the balls to move up and fight GSP, but GSP just sits there in the weakest division in the UFC like a chump. That's why I don't respect him. He undoubtely a great fighter, but he doesn't have the onions to take on the very best: Silva
