Oliver McCall has a great chin, but I haven't seen enough fights with him to see him get caught clean with a bomb, but if he was never down in his whole career and even as an amateur, he can obiously take a shot. Tua has a great chin, but he was down in the olympics and he was hurt at the end against Rahman. Vitali has awesome whiskers, never been down even as an amateur. Jake LaMotta never went down, but he was hurt when Sugar TKO'd him. Randall Tex´s only KO was supposedly a drug related payoff, and he was never hurt in his career. Toney obviously has a great chin, especially for his size, but he was hurt pretty bad and his legs wobbled against Peter Mavrovic was never down as an amateur or pro. Lewis can hit plenty hard, and he hit him flush 3 times in a row there, he just could not have hit him any better, and the guy just doesn't budge at all. For me, Mavrovic has the most impressive chin I've seen. He did get sick after than fight, lost a lot of weight and muscle, I don't think they figured out what it was and I saw an interview with Zeljko saying it might be psychological. He's now a farmer and grows organic stuff. Still has the mohawk.
a very underrated fight. unlucky for Lewis that Mavrovich retired right after cause he had the ability to make Lewis' record even better than it already is.
That's my pick! 15 plus years as a top ten HW, and was never knocked down. Lost a TKO to Foreman, but his corner stopped the fight. George fought most of the top guys during a great era, and NEVER went down.
The Bronx Bull............he took the best of the great Sugar ray and never went down. He also had the balls to face the man over and over when no one else would.
