For me, watching Floyd Mayweather box is never boring, maybe is because I do some boxing myself and know the details of the sport. What he does is extremely difficult... but yes, I can understand that casual fans only want to see huge guys with massive KO power like Mike Tyson and George Foreman.
It is still a very interesting fight to see because of its oddity of 2 mixed sports for the casuals so we will see. I just hope it happens so I can make easy money again thanks to Floyd since he should win.
I am far from a casual fan and I never said that all Floyd Mayweather's fights were boring. What my point is I know this fight will be over hyped just like the Floyd versus Pacquaio fight and it will not deliver the goods. Pacman versus Floyd was one of the most boring fights in history, and it was so boring that the pundits started declaring that boxing is dead.
Well, Pacquiao vs Floyd didn't deliver because of Pacquiao's fault. He was the aggressor, he should have breaken the Mayweather barrier, but he couldn't, so Floyd made him look bad. Pacquiao got some good hits here and there but that's that.
But let's not forget Pacquiao is old. McGregor is in his prime physically, I think he can be an aggressor for a long time, we will see what happens, but it will probably disappoint compared to the amount of money such a fight will raise.
