To me this fight did nothing for the sport of boxing but make Floyd a boat load of cash. Everybody won in this fight except the sport of boxing. UFC can boast that their top fighter went 10 rounds with arguably one of the best boxers of all time (at least on record and hype) . CM once again made a boat load of cash and he loses no creditability since he played under the boxing rules and made it respectable. To me UFC got bragging rights and the sport of boxing got a bit of a black eye.
Man, I don't see this at all. In who's eyes is boxing damaged? You can only lose your dignity if you have some in the first place.
These stupid sideshow things have been part of boxing literally from the beginning. This one was a little more high-profile, but stuff like this has gone on forever...see Ali-Inoki, or the night George Foreman tried to knock out four guys in one night. Or the time HBO broadcast a fight from a prison, because an inmate serving a long sentence was a contender. Every hear of Butterbean? Boxing has no shame.
Anybody that's already a boxing fan saw a non-competitive fight, saw a diminished and/or uninspired Floyd carry a guy who had no business in the ring for 10 rounds. McGregor didn't "get better hits in" by any means. People just lost their minds every time he touched him, because nobody expected anything from him. Everyone who's a fan of boxing is just happy to have this "fight" behind them.
However, the entertainment value was a little higher than some Floyd fights, thanks to McGregor's activity level, McGregor's antics, and Floyd being the offensive aggressor.
Hopefully, some casual folks that tuned in saw a moderately entertaining bout, compared to some of the others they might have tuned into in the years Floyd has been at the top. Maybe they saw that boxing, especially when there's a good live atmosphere, can be entertaining. Maybe they'll check out the Canelo-GGG fight, if that can get enough mainstream attention.
The only bad outcome would have been a snoozy 12 round hug-fest, or a first round DQ, or a stoppage on cuts, or something else that made people feel like they got nothing for their money. Which happens all the damn time.
In this case, both guys did pretty good by their sport...McG fought a smart fight that extended his time in the ring, showed activity instead of rolling over, displayed a little of his charisma, and didn't do anything highly embarrassing like getting disqualified. Mayweather showed offensive aggression he hadn't in years, carried his opponent and gave him enough to give fans their money's worth, and closed the show.
As much as the whole thing was an insane garbage-fest...this was probably as well as it could have went, other than everybody just ignoring it. It could have gone much worse in about 12 different ways.
