Yeah I've heard that. The best footage of any fighter I've ever seen was the beating he put on LaMotta in the Valentines day massacre.
He fights an awful lot like Salido. They fought in August of 1938 and it was Armstrong's TENTH fight of the year. Totally different era.
Remember if he was here now he would have better training better nutrition and the best advice He would defiantly be better than he was !
