Very few have managed to build a fairly successful boxing career that spans more than four weight classes from featherweight, super featherweight, lightweight, junior welterweight and welterweight. Juan Manuel Marquez is a certain all-time great like contemporaries Marco Antonio Barrera, Erik Morales, Manny Pacquiao and Floyd Mayweather as his name will always be mentioned in the same breath as theirs.

I say on down the line yes in the future and he was one of the best feather and superfeathers a five division world champion with a record of the 62 fights 55 wins 40 by ko and 1contriversal draw and will be metioned with pacman and mayweather in the future

yes i would say so , jmm is an amazing boxer who's only fault has been that he got beat by floyd and robbed vs manny pac .

Philip is an idiot of course he is a great.

Absolutely, he'd have been competitive in any era!

No way.
