Agreed I mean he boxed yeah great and maybe he could win boxing matches against some but mayweather has beaten the best of the best. There's levels to fighting and mcgregor hasn't had a boxing match in a long time and has been training under different rules and learning other stuff. Mayweather has been nothing but boxing training his whole career.Sure, no one is denying that Conor is a competent boxer. It's just that there is a huge difference between someone whose highest boxing accomplishment was winning an amateur all-Ireland championship at the youth level and someone who has won 15 professional world championships in 5 weight classes, is undefeated in 49 professional fights, and is considered by many to be the greatest pound-for-pound boxer of the last 25 years.
I mean, I'm competent at BJJ, but that doesn't mean I can hang with Marcelo Garcia.
Conor's one advantage is probably his age. He's 11 years younger and more in his physical prime. Even so, it would be a major upset for him to win under boxing rules. (In MMA the advantage would be his, but that fight isn't going to happen.)
