I like golf as well. :)
They are two of the most prolific trash talkers of this era. I don’t think McGregor actually means death...just trash talk. Keep in mind about Mayweather, he went to jail for beating his girlfriend, so not all in life was excelling. They’re both all about self promotion.
By acting like a nutjob, McGregor got himself a title shot before someone with his record normally would have. He leapfrogged in the rankings.
True. I forgot about Mayweather’s loathesome behavior. Yeah, the kooky talk is all about money, I know!
