What??? How can you compare Floyd's training to Hagler's training??? It's not possible, here's why. Marvin Hagler is an ATG who fought the best. He would fight anywhere, anytime, any place, even outside of the country. Floyd is a mere HOF'mer who is insecure and doesn't fight the very best. We don't know how great Floyd's stamina is. We know it's good at best. He's never had to fight 12 HARD rounds against opposition that could defeat him. He gets away with this low output per round in this era. He wouldn't get away with it in another era where EVERY opponent only knew HARD WORK. They would throw until the end. I question whether he can fight 12 hard rounds against A Level fighters, fight in and fight out. He wanted to retire after Hatton. He wanted to retire after Cotto. Maidana's pace bothered the hell out of him. Maidana won like 5 out of the first 6 rounds, in the first fight because of his pace alone. Floyd's condition would not survive the 80's or 90's. He is conditioned to go all night fighting at the slow pace he fights, throwing 40 punches a round. This is a major weakness.
Both have a great work ethic...but lets not sit here and act like Hagler fought in the best era of middleweights....Like most modern great middleweight champions, Like Monzon and Hopkins, his biggest wins came over guys moving up or former welterweight champions
Both are great but Mayweather is more accomplished and will be remembered as the greater fighter
Hagler...62-3-2(52 kos)...one lineal title, 12 title defenses, defeated former world titleholders/hall of famers(6)John Mugabi, Roberto Duran, Fulgencio Obelmejias, Tommy Hearns, Alan Minter, Vito Antuofermo
Mayweather....47-0(26 kos)....4 lineal titles, 5 weight title holder, 21-0 9 kos in lineal title fights, 25-0 over all in title fights....18 overall title defenses
defeated former worldtitleholders/hall of famers(20) Genaro Hernandez, Jesus Chavez, Carlos Hernandez, Diego Corrales, Goyo Vargas, Oscar De La Hoya, Miguel Cotto, Robert Guerrero, Sharmba Mitchell, Ricky Hatton, Canelo Alvarez, Demarcus Corley, Victor Ortiz, Shane Mosley, Juan Manuel Marquez, Zab Judah, Carlos Baldomir, Arturo Gatti, Jose Luis Castillo(2x
), Marcos Maidana(2x)
Mayweather has defeated more champions, won more titles/lineal titles, more hall of famers,, and has more title defenses in less fights...Mayweather ranks higher than Hagler who is more beloved but definitely not as accomplished
