You could actually criticize anyones resume the way you are doing it. I could make the argument that Monzon competed in a more diverse boxing landscape with allot of talent from around the world, while SRR or Lamotta only competed against fellow Americans.
Didn't look great on film at all. Looks incredibly slow and ponderous, his punches don't seem to have snap either. For all that he is arguably the greatest MW in history. Whilst there are many who might be quicker, more athletic or more pleasing to the eye, more often than not Monzon would find a way to get the job done and beat them.
Haglers best wins: Hearns ex welter weight Duran ex lightweight Mugabi Light middle Lost to Leonard , a welterweight having his first fight at middle weight. Hopkins: Daniels a light middle. Trinidad an ex welter ODH an ex welter Brown an ex welter Jackson a light middle . Leonard beat three men at middle: Duran an ex light weight Hearns an ex welter And Hagler Toney beat: Nunn McCallum Johnson Jones beat: Tate Hopkins Castro Monzon's resume is as good as any of them imo.
I agree that all of their resumes are surprisingly underwhelming relative to certain ATGs in other weight divisions. But while it's probably not fair to knock Monzon based solely on his quality of opposition, the difference is that those other middleweights look great on film and appear to have at least as much skill and demonstrably more natural physical talent than Monzon.
I'm always underwhelmed watching Monzon but he got the job done. He said " No I didn't win the title 5 times like Robinson, that's because once I won it I never lost it". Hard to argue with his results.
Monzon is the closest thing to a perfect boxer -Big for his weight class -Has the best style(long range jab/cross) -Versatility -ATG chin -ATG stamina -ATG footwork -ATG finisher
He'd be tough on Robinson because Ray like to fight fighters, and Monzon didn't take risks and used his physical advantages as well as anyone. He wouldn't engage Robinson.
Monzon would be tough for any middleweight in history. Great desire, conditioning, and chin. Range, power and heavy hands. People bring up Emile Griffith fight but how many times has an older past great come along and put on a good performance against a prime great. Happens pretty often, it's experience. Look at Holmes vs Holyfield, de la Hoya vs Mayweather and so forth.
Briscoe and Grffith were not past their primes, they were just unable to beat Monzon. One thing to keep in mind regarding Monzon: He weighed in well under 160 easy, and weigh ins were fight day. If he was competing now, he would be 154 pound champ. Imagine him at 154? No one today would beat him, including Floyd.
And remember, Carlos Monzon would not have let Roberto Duran last past the third round, tops, unlike a certain other great champion.
An old Emile Griffith took Monzon 14 and 15, Bouttier lasted 13 and 15, Licata lasted 10, even Napoles lasted six. Lots of undistinguished fighters lasted many rounds with Monzon, but Duran wouldn't make it past round three?
Q How many times was Griffith stopped? A= Twice in 112 fights. Q How many times was Bouttier stopped? A=Twice in72 fights.
Monzon doesn't look all that great but he was extremely effective with the attributes he had. His size, jab and power were a hard combination to overcome. Pretty good at controlling range as well. It all adds up to him being a tough opponent.
