Who had the most stamina?

[dempsey1919]

Jim Jeffries in his prime was able to KO you in 20 plus rounds.
Jess Willard KOed Johnson in the 26th round.
John L. KOed Kilrain in the 75th round in round w2ithout a time limet.
Jim Corbett was still as fast in the last round as in the first.
Marciano never once took a step back

as u get tired hits tend to make u more dizzy and off balance. so those late k.os mean nothing when it comes to power

good point.

the old fighters of jeffries time, were VERY good when it came to endurance, you have to put names like jeffries in the list, ali, marciano, frazier, john l.

Im not too sure about this but i reckon its between jeffries/john L/Marciano if i had to choose now it would be jeffries

[redxl7]

I would put frazier number 3, and ali second, cause he could dance and throw punches for 15 rounds straight.

Yeah your probably right, a prime Ali did have more stamina than Frazier.

Dance and throw punches aren't as hard as throwing left hooks with your whole body weight and effort in it the whole night long. Frazier was working a lot more than Ali, and Ali sometimes hung on the ropes, Frazier never did that. It was 100% full effort the whole night long. That is why i think Frazier had more stamina than Ali.

Of the heavyweight greats of all time, who had the most stamina? Of course, I'm referring to the ability to just keep going at a good pace. Not necessarily heart, but physical stamina.

Names that come to mind:

Joe Frazier - still had good power in later rounds.
Rocky Marciano - could punch until the cows came home.
Muhammad Ali - had the ability to finish guys off in the 15th.

While I've listed three obvious contenders, with very limited explanations, I expect much more from you!

Let the discussions begin.

i agree with those 3 they could all end a fight in the later rounds, ali had his moments where his stamina waivered but that was mostly ue to age in his prime he was one of the best

We are talking about Ali's prime.

LaMotta, Frazier, Marciano, Armstrong. Those guys were relentless, no doubt in their primes no one threw more punches and pressured more than these guys.

Oh, yeah I forgot about Armstrong.
