Best stamina in Boxing..

[Gandalf]

Joe Calzaghe and Manny Pac. Joe could do it until he was 36 though and Manny hasn't had that output for several years so Calzaghe wins this one.

Prime Manny was great too though.

Joe is an example of a clean hard working athlete who built up his stamina through dedication.

Ricky Hatton could had good stamina too.

Manny and Floyd come to mind. Had a lot to do with being smart in the ring and knowing to never over exert yourself (especially Floyd, who would often have entire fights without exerting himself at all ).

As for who has the best pure stamina, I'm not sure, because fight IQ plays a huge part!

Rocky Marciano

Loma

Trinidad had spectacular stamina, as evidenced by his amazing heart rate recovery time between rounds.

Hatton and Calzaghe were two of my favorite fighters, but Calzaghe had much better stamina IMO. Hatton had good workrate and pressure, but certainly in the last several years, I felt his stamina was on the wane. He struggled with Collazo in the second half, same with Urango, and I thought he was less than impressive against Floyd fading and flapping somewhat with the bogus point deduction. Was that stamina or red mist? Other fights and hindsight suggest the stamina wasn't quite the same. The self abuse had likely taken its toll somewhat.
