How was Lewis able to KO ruddock in 2 rounds but Tyson couldn't do it?

[check hook]

Tyson's a more aggressive fighter than Lewis, so why is it that Ruddock withstood so much of Tyson's beatings, but Lewis was able to get him out of there in only 2 rounds?

Mike virtually took Donovan's soul. He beat the prime out of Ruddock. If you don't believe that you need to rewatch their fights, he really took alot of huge shots from Tyson. Lewis got to him a bit after. Can play this game all day anyway. Why was Tyson able to knock out Frank Bruno earlier years before Lewis fought him? What was it that Frank Bruno said "I'd rather fight Lennox Lewis a 100 times than Mike Tyson once"

Sean Newman: You were expected by many to win your fight against Lennox Lewis. What happened in that fight? Did you just get caught?

Razor Ruddock: Yes, I just got caught, but realistically the fact of the matter is that Tyson and I finished each other. Lewis fought a shell of us both; he would have never wanted to fight us when we were still fresh. It's true, he got a shell of us, and we weren't the same after we fought each other. We fought two brutal wars. His eardrum was busted in the second fight and my jaw was broken, and we were just never the same.

i typed my reply without having read this. Interesting that iv'e never seen it but he agrees with my assessment. I thoroughly thought the fights took something from both men but mainly Ruddock. Again people need to go back and watch them. Shocking what they were landing on each other.
