Modern fighters that would have done better in 15 round + fights

I don't know, if you could say they would have benefitted from fighting 15-rounders... but Pac and Calzaghe certainly looked, like they could go more than 12 rounds without gassing.

 

Floyd comes to mind. He had great stamina, fought at a measured pace, and was relaxed. I don’t imagine 3 extra rounds hurting him.

Hagler mostly fought 15 rounds title fights, The Leonard fight was an exception.

 

But how can Mayweather do better then going undefeated officially?

If anything him typically fighting pressuring power punchers for three extra rounds might actually decrease his chances. Imagine if Castillo got more time with him in those fights.

 

I agree with Pacman, Chavez, and Calzaghe.

Here's one Holyfield in his HW years.

Golovkin? He seems like a well oiled machine that could pace himself.

MAB and Morales seem like 15 round fighters.

 

Ward
Hopkins
Mccallum
Mosley
M Taylor
Pacquiao
Porter

 

Felix Trinidad would of had no problem with the 15.

 

Believe it or not ....James Toney....he was so relaxed in the ring...and in a 15 round fight he could actually rest more

 

Golovkin. He has an economical style and tends to be relaxed and methodical. He's usually going harder in round #12 than #1

 

He never really needed it!!

 

Lomachenko starts slowly and has good stamina and is relaxed. Estrada too is another who starts slow and comes in.

Marquez would have been fine with 15, and Chavez surely too.

 

Tyson Fury has that old school heavyweight aura to me.

 

Carl Froch

 

Larry Holmes would be my pick as best in any era of boxing. Nice jab, mean hook, Penn state champ wrestler and the mentality to dropkick a mother****er.

 

Huh?
