Mares losing was the biggest surprise but Broner's image and standing fell further from one fight than anyone in boxing history so i voted for Maidana.
I was surprised at how badly Broner looked but not the upset of the year IMO. Broner really disappointed me, all the acting and lack of focus, so I would vote for him as biggest let down,:nut forsaking the 147 jump, based on his poor :|performance with Maidana. :smoke
I think more people gave Maidana a chance over Broner before their fight than gave Gonzalez a chance over Mares before their fight. For this reason its got to be the Mares fight.
