Castillo pushed Floyd' s **** in the first fight and got robbed. Imagine what he would do to the Floyd clone! Damn nicca!
Considering how Castillo handle Floyd the first time, and Floyd was a better fighter then, then what Broner is now. I'll give the fight to Castillo. Broner defense is not as good as he thinks, and he gets touch a bit much. He also has a low work rate. Castillo would of gave him all kinds of problems.
This is pretty much it, except you may be understating just what a beat-down it would be. :yep Castillo >>>>> Maidana Mayweather >>>>>>>>>>>>>>> Broner
