ali, frazier, johnson, foreman, tyson, liston, louis thats 7 already greater than lewis IMO, dont get me rong i love lennox but i think hes more an 8-12 all time heavy, but feel free to disagree.

now as for tyson --

a peak tyson would of taken out lewis, we saw in the holyfield fights lewis does not like to fight in fast exchanges, he would be puffed out by the 8th round if he got there, thats not sayin hes unfit but he is a large large man and so would have tired earlier. tyson in his prime i believe is underated by many, remember people thought that tyson was going to be the greatest heavyweight of all time.... therefore he must have put on performances of that merit, he just peaked early thats all like all fighters of his build and style. now dont say thats like thinking amir kahn was going to be the best lightweight ever because he hasnt won a Wt yet, tyson had unified them remember...
