I think Floyd of five or so years ago would have had a good chance at 154, especially if Golovkin was any worse for wear having to cut the weight. Manny is even smaller than Floyd and with such a physical style I don't think it would have been realistic for him to fight someone as big as Golovkin. Look at Manny against Margarito, he was basically fighting the size difference all night, in what was in every other way a total mismatch and beat down.
