I'm not a Golden Boy groupie, just a boxing fan who can't help but notice that Top Rank is on the decline and Golden Boy is taking over. Not saying it's good or bad, just noticing it's happening.
GB has 11 champions right now against 3 for TR
GB controls the JMW, JWW & BW divisions, TR doesn't control any division
GB has 3 cash cows (Floyd, Canelo, Khan) against 2 for TR (Pacquiao, Chavez Jr)
I would say that GB has 3 guys that could become cash cows in the near future (Broner, Garcia, Guerrero) against 2 for TR (Bradley, Rios) but that's subjective.
GB has the most promising prospect in boxing : Gary Russell Jr
TR has no recognizable heavyweight, GB has Mitchell and Wilder and I think they have some sort of promotional deal with Haye.
All in all, I think it's the beginning of the end for TR. Not sure what it means for the sport of boxing as a whole.
