I'll start. 1st thing that comes to mind about him---and I dont know why---is his 2 knockouts by McCall and Rahman and to a lesser extent his last fight with Klitschko.
You never saw Marciano or Ali or Foreman or Holmes get smoked/sparked with a single shot stone cold out. So it does have an effect when we recall those facts in Lewis' career. Yes Schmeling KO'd Louis but it was a combination left-right-uppercut-left I think. And of course Rocky smoked Joe but he was already old. Was Lewis old when McCall and Rahman got him? Dont think so. 1999 and 2001 right? That is still in his prime isnt it.

I rank him in the top 10 alltime great but I sometimes wonder where he actually belongs.

What criticism if any would you have about him?
