I think Bradley kind of messes up "the natural rivalry" between the older guard, better established fighters Pacquiao and Juan Manuel Marquez....but it's not his fault, he's just fighting the best out there now and to his credit he's beating them more often than not. The fight vs Provodnikov is something that needs to be revisited, I think everyone agrees to that.

Bradley would have been the perfect foil at 140 for Hatton and Cotto, maybe Judah or Mosley as well. Those would have been nice to see. I welcome him as a fighter, he's respectful, he's a good person outside the ring, a hard worker, he gives his heart in the ring. He deserves to be respected.
