What kind of money would he make vs Brook ??? I'd guess this is a PPV stadium fight in the UK = big $$$$ and Khan would have at least 50% if not more of the pot! vs Mayweather he'd be on a much smaller %age...would that really be bigger financially for Khan than what he'd get vs Brook ? I'm not sure....seems Khan must think there's more money vs Floyd but I cant see it as Floyd would be demanding the biggest part of that pot and rightly so here.
The money fighting Mayweather will be so much more, it's not even worth comparing those two fights. The only thing I can tell you is, Khan vs Mayweather will be on PPV which is guaranteed to sell big while Khan vs Brook will be free(probably on PPV in England only).
Thing is, Khan can probably do both those options if he gets the Mayweather fight first, loses as we all expect while gaining more exposure... and Brook having a couple of fights in the meantime will make the Khan-Brook fight huge.
