How does Floyd Mayweather vs. Conor McGregor play out? I'll put it this way: Nolan Ryan is considered an all-time great pitcher in baseball. If you put him in as the starting quarterback in the Superbowl, the man gets killed. It doesn't matter that he has a good throwing arm- there's too many other variables, techniques and tactics that he's wholly unfamiliar with. Likewise, Joe Montana is an all-time great quarterback in the NFL. Put him in as the starting pitcher in the World Series, and he gets melted either by walking every batter or getting a ton of home runs scored on him. I'd compare McGregor vs Floyd as a pitcher vs a quarterback. They are in totally different sports. Just because both a pitcher and a quarterback can throw hard and with precision is not enough to make that leap across to a new arena at any type of competitive level. In boxing, Floyd absolutely kills McGregor 99 times out of 100. (In any fight, there's always the slight chance of that knockout shot, and McGregor has power.) In MMA or kickboxing, Conor melts Floyd with relative ease. The promotion leading up to the fight will be absolutely tremendous and a ton of fun, but once the bell rings, it's an amateur sparring session for Floyd and I think a lot of people will be disappointed in how uninteresting the fight itself ends up being.
