Broner's decent but his stance has positives and negatives and the negative of having a wide stance is footwork being hindered and at times Broner for all his speed of hand can look sloppy on feet and fall out of position. He'd open himself up to Gamboa, Also if he fought a conservative fight he'd most probably get picked off. Gamboa would win the footwork war and thus winning the fight. Broner's got a way to go but he's good, needs to fight a world class fighter soon though..
I think some of us are selling Broner short. He looks pretty good to me and i've always had my reservations because you have to know what you're doing with the way he fights (as we saw with JuanMa's attempts). Broner is an improving fighter though. I think he's legit. Not on mount rushmore yet, but he's heading in the right direction.
