Antonio Margarito. Self-branded himself boxing's most feared fighter and sure, that one guy's ear practically being torn off was gruesome but what else? Seeing him smile while the other guy hesitantly punched him wasn't impressive to me. The guy has shit for defense and Paul Williams showed how scary he is. Joshua Clottey spanked him until injuring his hand. The only people who should be afraid of him are guys who have no hope of breaking through the top ten.
