Evander, Oscar, and Bernard have the best resumes of active boxers (Yes, Evander, cause you never know if he's actually retired or not). No need to restate them, they've been brought out in this thread already.

Also, I think Pacquiao is up there too and his list is still growing. Not to mention second-rate fighters he's faced but the elite list is serious!

-Barrera
-Marquez
-Morales
-Morales
-Morales
-Barrera
-Marquez
-De La Hoya

Imagine if he is to fight Marquez again? Hatton?
