If and its a big if, he wins, he can legitimately call mayweather out. He would come out of retirement to win a belt at another weight. If he loses the Brook fight will still be there so he’s quids in. I’m not khans biggest fan but he’s got balls and will fight anyone.
I thought boxing was about fighting the champion and winning belts not calling out 38 year olds who are retired(no matter how good he is),why would he do that? for the cash that’s why,khan just wants a last big pension.
