Iron, Average or Poor? I say iron, he took monster punches without going down. Just look at the uppercut he took from Lewis. Any other HW would be out cold.
That upppercut that sent his face looking at the ceiling from Lennox Lewis may have been the best "take" in the history of boxing. Duran had one, can't remember the opponent but he did a grin. Grin gets his kudos. But I think the punch Vitali took was a mutha****a.
