Based on 50% career accomplishment and 50% future capability: Gonzalez Ward Klitschko Rigo Kovalev Golovkin Pac Everybody else
Their standards beg an explanation. Klitschko was a world champ and has been undefeated for a decade. A decade ago everyone who outranks him except Pac was unknown to public.
Go before that and he was robbed against Bradley and lost to Marquez in a fight he was winning. Earlier than that and he was looking good. It's not enough of a fall off to eject him from the rankings, although #3 is a little high.
By Manny's standards wins over Rios and Algieri are average wins but that's because it's Manny...they're good wins for any fighter
If you combine the total number of title fights Rigo and Ward have, you still have five less than the number of knockouts alone Wlad has in them.
