The man only has 25 pro fights. If anything, his record is that good because he has fought so few times.
Haye has done fairly well at heavyweight. He fought SNV, which is something neither of the other belt holders managed to do. He beat Ruiz pretty good. The problem with Haye is that he talked himself up so much, that anything short of trying to become undisputed champ is a let down. Then, he turns down his chance at unifying and decides to fight Audley...that is the joke part about Haye. And that's a huge joke! Which is why I hope Audley knocks him out.
