This quote from Hopkins got me thinking - What fighters could compete in any era?
Certainly skill-wise, I believe Mayweather could have competed in any era, but to make it to 100 fights? To fight every few weeks? Never. Any fighter that can't stay in boxing shape 365 days of the year is also out of the mix. Fighters like ODLH would struggle to be stars in an era with 15 minute rounds. So who could compete? The Klitschkos? Hopkins? Mayweather? Pacquiao? Martinez? Ward? Etc.
There's the P4P, but taking a look at the Era4Era is also interesting. Would anyone in today's game put up a fight against Robinson? Lamotta? Willy Pep? Marciano? Ali? Frasier? Foreman? Moore? Louis? Patterson? Hagler?
And on the otherside - Which fighters could you speculate being durable enough (mentally and physically) to survive ~60+ fights?
