Unless Bradley gets careless and decides to brawl with Maidana, i genuinely believe he has an easier time than Floyd.
Just based on how they've looked this year I might pick Maidana in a slight upset. Vs Bradley Marcos will actually have the physical advantages in height, reach, power. Bradley also doesn't clinch a lot which is needed to slow down and force Maidana to reset. There corners are about equal Garcia and Diaz are both considered 2 of the top trainers, Bradley is a good boxer but he likes to fight inside and rough you up which would play into Maidana's strength. Both have shown suspect chin as well as a lot of heart only Maidana has the power to exploit it though. Although I don't think so a very legit argument can be made that Bradley should be 0-4 @ WW and even though Pac/JMM are good names neither of them has ever beaten a prime top WW. Maidana by SD or TKO.
if it happens next Maidana stops Bradley in 8 rounds. Bradley has taken far too much punishment in his fights against Provodnikov and Pacquiao. Despite Maidana losing his last two (to Mayweather) he made both fights competetive and relatively close and wasnt buzzed once so hed be going into the fight fairly fresh People picking Bradley to win are too nostalgic and are living in the past where Maidana was a limited fighter with no jab and Tim Bradley was a fresh young undefeated champion . . . . Maidana has improved and bradley has declined Id rather see Provodnikov Vs Maidana and Bradley Vs Algieri, the styles gel well and would make for 1 exciting fight and the other a technical chess match. depends on your preference really
