Sal Sanchez comes to mind. Wilfredo Gomez came up stairs. Carlos Monzon of course in Napoles or Griffith? Depends how you wanna rate them. Marvin Hagler and his win over either Hearns or Duran. You get the point.
Hopkins > Trinidad, Wright, Brown, De La Hoya. He did have good wins over Pavlik and Tarver to counter those bully insinuations.
He also robbed the fans of epic prefight smack talk and a high-level showdown with Lights Out at 190 lbs.
Absolutely right. The best wins might not be the best performance. It's the best win. There's a difference. Often, that's because the guy they beat for their best win was a champion and well-known. Many times, the best wins might not have been the best performance. That may well have come against a lesser known fighter at the natural weight of our top tier fighter but because this opponent never had the kudos of being a champion, albeit at a lower weight, it doesn't get the attention of the so-called best win.. Take Hagler. Noted for his wins against Hearns, Duran, even Mugabi; all fighters from lower weight classes moving up. But I'll bet his best performances were against the likes of Scypion, Hamsho, Sibson, Watts - natural middles all.
Aside from Young Corbett III, the biggest names on Jimmy McLarnin's win ledger qualify. Ross, Canzoneri, Ambers, Mandell and Petrolle, were all notably smaller than him.
Jake LaMotta. Jake’s 160 1/2 to Ray’s 144 1/2. Of course that was Jake’s way — fight welterweights and even then usually come in over the middleweight limit. He had weight advantages from 8-15 pounds in a LOT of his fights, especially against ‘name’ welters. Notice how it didn’t often work the other way. Never saw Jake come in at 162 and fight a full-blown light heavyweight.
