Emile himself fought top opposition and one of my fav. fighters...
Monzon, Paret, Moyer, Fernandez, Rodriguez, Ortega, Dupas, Carter, Curvis, Gonzalez, Fullmer, Tiger, Archer, Nino, Napoles, Boggs, Muniz, Lopez, Bouttier and on and on...

Thing is most fighters from back in the days have top resumes compared to todays fighters. Longevity of a career for starters contributes to that.

Of todays fighters Oscar De La Hoya, Evander and James Toney have some of the best resumes. B-Hops is also good.
