1) Michael Loewe (Born 1969, Welterweight) never fought Ali.
2) Ricardo Lopez (Born 1966, Light flyweight, Minimumweight) never fought Ali.
3) Terry Marsh (Born 1958, Light Welterweight) never fought Ali.

5) Dimitry Pirog (Born 1980, Middleweight) never fought Ali.
6) Edwin Valero (Born 1981, Lightweight, Super featherweight) never fought Ali.
Because ALL of them were A) Born before, at, near or after the peak of Ali's boxing career, and B) never fought a heavyweight bout in their careers.
Sit down liar. You've been TKO'd.
Looks more like you just TKO's yourself (AGAIN). So what if they didn't fight Ali ? Like he is supposed to be some standard that everyone might be gauged by ? How absurd.
He was a good boxer who was champ for awhile, but he got beat by a variety of different fighters. One of them (Leon Spinks), a low ranked almost unknown boxer, took the title from Ali, when Spinks was a rookie fighter with only 7 fights under his belt.
As for fighting a heavyweight, Rocky Marciano was a heavyweight (you obviously don't know what you're talking about), and what does it matter ? Clay called himself the greatest, not just the greatest heavyweight. He was nowhere near the greatest. Every one of the undefeated fighters I listed, were the greatest, and they EARNED that distinction by going undefeated, not by running their mouths, and calling themselves the greatest.
