Mayweather ez, never tires in any match. I wouldn't be surprised if he could fight 20 rounds and not even tire. Crazy conditioning Hagler was sick, but isn't near the level of Mayweather in conditioning.
Technically it's Hagler, because he fought when 15 round fights were still around, but Mayweather has insane conditioning and I can picture Mayweather easily lasting 15 himself. But in all honesty they're about the same. Both completely ready to go the distance.
Maweather is well conditioned but a big part of it is that nobody can push the pace against him. He gets to fight at his pace and pick his spots most of the time. Cotto pushed him a little bit in spots but he couldnt sustain it. On the other hand Ive seen Hagler fight for 3 minutes a round and get stronger as the fight goes on. Defintely Hagler.
Are we comparing the stamina of the most past prime Mayweather vs a prime Hagler? I dont think its an unfair comparison.
Hagler without a doubt. 15 round fighter who could have fought 20. Ran 10 miles a day while in camp. His camps were also 12 weeks long.
I dont agree. Hagler didnt hit the bottle til after he retired. P4P neither Hopkins or Mayweather could fight at Markins pace over 15. He'd make em work when they dont want to work.
