This is probably not going to be much of a fight. Atlas is right. If the most skilled boxers could not lay a hand on Mayweather in the ring, then I am not giving much a chance that Mcgregor can do it.
However, there are some intriguing aspects of this. One, Mcgregor has boxing skills, so he is not really a slapdick. IF Mayweather takes him lightly and believes the media (which will all be making fun of Connor and we all know why the media will be hoping beyond hope that Mayweather crushes him) then CM could catch him.
CM will be using an unorthodox style that Mayweather has not seen. CM has a tough ass chin. Mayweather does not nor has ever really had much punching power.
There are factors that make this interesting.
