Joe Louis. Dominated the division like nobody before or since. Ali a close second. Marciano in the three spot. Dempsey next.
I vote Ali- his longevity and ability to rule the division in its toughest era- even though he was past his prime himself- speaks volumes
Funnily enough for the record, head to head, I actually think Lennox Lewis would beat them both at his absolute best- although he's certainly not the GOAT of the division- lower half top 10 at best
Muhammad Ali because he beat the strongest group of HWs in history & IMPO looked the best fighter of the lot when at his peak.
I don't know. I go back and forth on that. I can actually see both Louis and Ali schooling Lennox, but he could certainly knock either one of them cold.
