If Broner wants to become a crossover star, hanging around at lightweight isn't gonna get him there. The only fight with any crossover appeal is Gamboa, which I believe is the reason he wants to hang around. And that fight is such a mismatch from a size and skill standpoint, I can't see a smart business man like 50 pawning out his golden goose for that thrashing at this point.
IMO, the perfect fight for Broner is JMM. JMM's stock has never been higher. And because of the way the fight ended with Pac, it completely overshadowed the fact that the mexican legend looked like **** for most of that fight. I would make Broner a huge favorite over JMM. And that's the fight that crosses Broner over into the mainstream. No one at lightweight does that for him.
