Mayweather could have beaten Hearns at 147, and so could have a younger Winky WRight if he fought with his current style. I think Oscar Dela Hoya would have been able to take Hearns' right, and was good enough to take out Hearns. Castill, Corrales, are both greats. The only reason why Duran and Hearns and Leonard and Hagler are considered such greats is they fought eachother... IF they were in individual eras. They would have been considered good, but not great... Hell Hagler wasn't even considered great until he ko'ed Hearns. People thought that his close fight with Duran proved that he wasn't an ATG, and thats why Hearns was going to beat him.
