Thread of the Year

My finally take on this manner is that '67 Ali would outspeed any fighter in history. Or even 1965-1968 Ali as well. Frazier would've HAD to fight Ali WAY SOONER THAN MARCH 8, 1971, had Ali not been revoked. By 1968 or '69, an Ali-Frazier fight would've been forced to challenge for the title.
In 1968/69, a continuously active Ali would have whipped a younger, less experienced Frazier.

Prime Evander would dog the hell outta Ali but land few shots, maybe a boring fight due to styles. Can't picture Evander trying to cut the ring off for 15 rounds. That's just not his style.

Lennox ' s size would be tough for Ali but Lennox had shit stamina (and Ali would knock him out by the 10th or 11th or 12th round. I can see Lennox gasping for breath by about the 10th round and then Ali would just slice him like a razor blade. Ali wood pretty much due to Lennox Lewis what he did to George Foreman, it would just take him about 5 more rounds too do it. Ali TKO 13
IT WOULD SORT OF LOOK LIKE HOLMES VS COONEY.

Marciano and Dempsey would be too small

the only people I can think of at this may sound crazy but what about a prime Klitschko?

What about a prime Jack Johnson or Joe Louis?
