Care to elaborate? What I think you are trying to say is a logical fallacy since I think we can compare fighters based on performances even if they haven't fought each other. For example I thought Floyd Mayweather was better than Tim Bradley (when he was undefeated) even thought they had never and would never fight.
No, I think Haymon is clearly the best promoter in the game right now and that's the primary reason why so many young fighters pick him over the other promoters. Compare the career arc of Errol Spence against Jesse Hart, who at one time was a better prospect. They both haven't really fought anyone yet but the sheer promotion of Spence has him on another level right now as far as expectations and probably also paychecks.
Now that I've addressed the diversions do you care to actually answer the question in the OP?
In terms of getting fighters paid, yes he is the best. Matchmaking needs to get better tho. Although, he's had some good matches set up lately.
Canelo isn't a JMW anymore. Even if he was, it wouldn't matter. Lara is the best in that division. So, to answer your question, yes.
He beat Lara.
pbc is trash
hopefully thurman goes to goldenboy for some real fights
there's nothing for him with al heyman after he beats porter
He said he wants Gift if he gets pass Porter. That will look good on paper. But I think One Time smokes him.
