Crickets. Broner is one of the many reasons why boxing was so much greater back in the 'old days'. Back in the 50's or 60s, his loud dumb ignorant arrogant obnoxious ass would be put in it's place right quick, and his potential would probably be reached. It's a shame cause he's a halfway talented fighter that could have been better.
Imagine if that fool had to step into a weight class with guys his own size and fought the likes of Burley for his trial by fire.
