At his best, Gamboa outboxes him. He has the mobility to go in and out on him and use his shorter height as an advantage (kind of like Rees did to go to the body). One punch could change the fight though, Broner hits hard. Hard to say, it comes down to who looks more disciplined. Also doubt Broner is gonna drop down in weight again.
I think Broner hits hard enough to put chiney Gamboa down. Gamboa would land on Broner, but in doing so he would leave himself to wide open as he often does. Real exciting fight, but I see Broner winning because of accuracy, size, and a better defense. This fight would have to be at 140. That's where I see Broner going back down too. It should be his optimal weight for being only 5'7.
Lets see how Gamboa looks tonight @135lbs first... Broner looked like a BEAST @135lbs, **** dude is jacked @147lbs I seen the pics... lol Had this gone down last year my cash would have been on AB.
