Tyson had 16 KO's and Lewis had only 8.I would think that if a guy can't get up to his feet at all that must tell you that he has been hit harder than if he did regain his bearings and risen to his feet.

I also believe Wladimir Klitschko hits harder than Lewis.He has 16 KO's like Tyson.Wladimir has stopped guys that have great chins like Byrd,Brock,Nicholson,McCline,Mercer(TKO 6 while it went all 10 with Lewis),Shufford,Barrett,Bostice,Castillo,Wolfgramm ......
