Lenni nuhuggers had to make a video to desperately make a case for his jaw. History will remember the two one punch ko's and that is a demerit on his jaw for eternity
These shots would have decked a lot of heavyweights, specifically Tua`s hook, Lewis has a far better chin than Moorer did.
Oliver McCall is one of the physically toughest human beings I've ever seen. Possibly the toughest. He was one of Mike Tyson's main sparring partners when Tyson was in his prime. Tyson used to go full tilt when sparring & McCall was one of the few who could handle it. When Tyson stopped sparring with McCall, he dropped off significantly. It was an important factor in Mike Tyson's decline (imo). On the subject of sparring, that was one of the main reasons Oliver McCall beat Lennox Lewis in their first fight. Emmanuel Stewart (who trained McCall, not Lewis, at the time) had McCall sparring with Darnell Nicholson in the lead up. Nicholson wasn't a big name heavyweight but he was good enough to represent the US at the Olympics in the heavyweight division & was an ideal sparring partner to prepare McCall for Lennox. So it wasn't so much a "lucky punch". The untold story of how fighters win these fights is all in the preparation.
