This size and power connundrum doesn't exist. Ali/Foreman? George was a total destroyer, lot bigger than Ali and crushing everyone around. (Remember that punch that lifted Frazier right off his feet? ) Ali, had a plan, and slayed the giant. There are other parables of course, but Mayweather, like Ali, is a totally schooled, and brilliant defensive boxer. He won't have any fear whatsoever of Conor's physical advantages. And people are seriously underestimating the skills of a real world class boxer vs someone who has a bit of lower league boxing in his arsenal. Conor will never have been hit as accurately and systematically (powderpuff, or not) like he will be by Mayweather, Then there is the stamina issue as well, after 4 rounds Conor will be gassing like Jan Molby chasing after Usain Bolt. Nah, the fact is, Conor's skills are thinly spread to suit his own discipline. He's a jack of all trades, whilst Mayweather is a MASTER of one. It will be fun seeing Conor fly out and try and lay it on Mayweather, (does anyone really think he will come out in an orthodox boxing stance??) then it will all pan out into a big fat red face for the Irishman. (Literally).
