You really believe that. Ruslan Chagaev, who is smaller than Lewis, did that fairly well. Even Ruiz ran him close. Woddy, are you really serious.
Or Marcellus Brown, he's still going. He's 7 foot tall...I remember Tommy Morrison decking the big guy in 3 rounds back in 1995. And how about Choi Hong-man? He's in K1, but it's a similar occupation and he's slightly bigger than even Valuev.
