Broner is still a C+ fighter, Mosley is D- at best at this point, he'd get lit up and it'd be a joke, he already took a beating off Canelo, Mayweather and Pacquiao, he'll get one last cheque though regardless because that's how the sport goes.
I don't know if Broner is lighting anyone up these days. He looked really un motivated against Porter
He did manage to drop porter & steroids makes your bones become glass, chin is bones ... glass chin ?
