I honestly think there was a lot higher level of competition back in the SRR era than there is now. There were more professional fighters in New York than there are registered in the entire world today and they were literally coming from hunger. No crybabies quitting fights because they got a booboo on their eye or at least nobody anywhere near world level.

Give those old timers modern nutrition and training and you could count the number of modern-day guys who could hang with them without having to take your shoes and socks off.
