So, lets go with Chuvalo.. the most granite chin in history..face foreman, ali,frazier etc, and never came close to touching the canvas

Penalosa, Donaire, Juanma Lopez?, Chagaev?, Povetkin? ----------- Johnson versus Sheika (4th) Sanchez - one slip on the ring edge versus Escobar but ruled a KD [yt]http://www.youtube.com/watch?v=USxJeHV1pd8[/yt] Watch the last ten seconds of the 1st round Much more of a KD than for Hagler or Sanchez. Vitali was doing his best Wlad impression in the first round (running backwards, looking like a novice, panicking, flailing, falling). On a side note: Watch the 1st round of Vitali Bambi Klitschko/Corrie Pop'nFresh Sanders and ask yourself is this really a great big man or just a big man?
The only other TOP, current fighter I can think of who hasn't been Kd'd is Humberto Soto. He's had a lot of fights, too. Maybe Dzindziruk, too, but I'm really not familiar with his career at all.
Australian Barry Michael faught in some of the most punishing battles in the games history. The man was a complete 'cement head'.... his old nickname. In 61 pro bouts, Barry never touched the canvas. To take a glimpse of his 'hardened head' look for Lockridge vs Michael. The guy is a tough, old school man.
jake lamotta was knocked down by danny nardico.in my opinon if you are countain hagler as having been knocked down then it was a foul as he was hit on the back of the head.
Let's be honest, Hagler was never legitimately dropped. Chuavlo was stopped on cuts by Foreman, but never down as far as I can recall.
