"My big brother got his legacy, I got mine," Broner said. "I want to see him retire undefeated. I don't want to hand him a loss."But I do recall Broner having declared he wants to gross a billion dollars when all is said and done. It's a given that a fight with Mayweather would bring him $10 million dollars or so closer to that goal. That doesn't entice him."It's not about money," Broner declared. "I ain't hungry, I'm fine."
