Ehh...neither. Boxer-puncher sort of fits, I guess. But on that note, I think you have a poor understanding of what styles are, or how people use the broad categories that have been widely accepted to describe. They are just that - broad strokes. Fighters are not Pokémon cards or elsewise like collectible trading cards ultimately reducible to a combination of this or that attribute. Stylistic labels in the common fan parlance will not always neatly fit each individual fighter. Some may have none of them, or multiple (or bits & pieces) apply. Just by the way you've asked the question I can tell how little you understand. No offense.
Mayweather carried him for 10 rounds to give the fans their moneys worth. Imagine Mayweather teeing off on McNugget in the first 30 seconds and knocking him out in the 1st round? It would have devalued the UFC overnight and Showtime and the promoters would have struggled to create other PPVs at that price point again. The public would have felt robbed and not dipped into their pockets for a long time. Floyd would also have been persona non grata too for ruining a huge future revenue source for TV networks.... But yeah.....Floyd carried McNugget for 10 rounds and could have finished within the first 60 seconds if he wanted to. We're talking about one of the BEST ever boxers here against a zero fight novice.
Style? he has no style, because he doesn't know how to box therefore he can't be assigned a style . As has been pointed out Mayweather could have ended this inside a minute. It was a sham
Seeing as how McGregor was throwing hammerfist on a couple occasions, Id go slugger style. He had zero chance.
How the **** anyone see's it any different to this i'll never know...Big fight fans, passionate fans robbed of their brains on this analysis..1 round fight if legit, no way Mayweather slipped that much
Same, the eyes of the world were on the match so Floyd wanted to make a show out of it. he could of done what he did to end it in round 3, it was a circus fight that made them massive dollars
