As for all this “A side” and “B side” stuff, it’s simply Mayweather saying he should get top billing in the fight and everything that comes along with that: the ability to dictate prize purses, fight location and date, etc. Whether such a fight — between a boxing champion and an MMA fighter who never has trained as a strict boxer — should even take place is another matter entirely.
Mayweather hasn’t fought since September 2015, and for much of the past year he and McGregor — the reigning UFC lightweight champion — have been jabbering about fighting each other. Mayweather said Saturday that he’d like the fight to take place in June, but McGregor is taking time off ahead of the birth of his first child and won’t begin training again until May at the earliest. One would think he’d like to at least have a few months to, you know, learn the sport.
There hasn’t been any comment from McGregor over Mayweather’s latest proclamation, but he did tweet out a photo of one of Mayweather’s “Money Team” vans on fire the other day. So there’s that.
