Whoever can get Adrien the best fights & the most $$. His affiliation should make no difference to us as fans.
I doubt they are going to sign fighters to high-paying contracts just to throw them in with one another right away. Hell, Knowing the way Al Haymon operates they will continue fighting scrubs on HBO for ridiculous money and never set foot in the ring with each other. Besides, Gamboa is too small for Broner. It's as much of a size disparity as it would have been against Rios. Broner is as big as a Welterweight.
