I think the fact he went ten rounds was an accomplishment. Mayweather is an all time great and a tactician so there was no question at all he could pick macgregor apart with ease.
I'm saying macgregor accomplished more because he got a payday he never would have gotten in MMA and didn't completely embarrass himself.
Anyone who expected a novice to be able to compete with Floyd was insane and just bought into the hype machine.
Now if it was Floyd and macgregor in a barroom and chairs and bottles are legal, I'd pay 100 to see that.
