It's nothing curse people associate themselves with Mayweather for promotion, but when they lose it goes south
Same thing happened to Adrien Broner, he called himself lil bro, he was the next mayweather, he gonna break mayweather's records etc
Once he loss to Maidana his career has never been the same and he has zero hype next to his name compared to how it was
The thing is Ronda and Mcgregor at least got paid for riding the mayweather train
but in all reality instead of taking shots at him they should've just joined the money team lol, and kept a healthy association with mayweather because once you lose nobody wants to hear you mention Mayweather's name
But a lot of time it's MMA media asking them about mayweather and they start feeling themselves
