The Floyd who could of fought Golovkin was not only still massively undersized and outgunned power wise but also old and faded. Only someone desperate to see Mayweather KO'd would think it needed to happen and if he somehow in his late 30's danced his way to a decision it would have been denounced as running and calls would of been made for him to fight SMW and LHWs.
GGG is as quick as Conor was vs a sluggish Mayweather, if Floyd fought how he did vs Conor he wouldn`t last two rounds with GGG, he`s almost completely finished at world class level and counting, GGG has far more left in the tank and is better than anyone Floyd has ever fought.
Good grief...people act like it would be a 135 version of FLoyd in the ring w/ 3G if they ever fought. 147 and 154 version didn't have the mobility as the lighter version 3G KO Fluid..
Floyd gets pinned on the ropes. Floyd also doesn't mind fighting against the ropes. GGG is an exceptional ringcutter, too.
Honestly Floyd couldn't even get to 154 in his 4 fights there so I highly doubt he'll make 160.. He won't have a problem with weight...
