Well, this is why I didn't bother betting on this fight. I really wanted McGreggor to win also, but just felt like Mayweather was going to be too much. Oh well, it's why he's the champ and has been for years.
McGregor came out with plenty of energy and was the aggressor the first few rounds. Even won a couple. But he tends the win his MMA fights quickly. He wore down big time. And that played completely into Mayweather's wheelhouse.
Mayweather has no problem going the distance. He plays defense. Better than any boxer in a generation or more.
Kudos to McGregor for going as long as he did. The match swung heavily in Mayweather's favor the longer it went. He's just been doing this all of his life. 50-0 is no mistake.
