I think it would be bigger for their respective careers. The mega fight will effectively be the passing of the torch. What better way to signal that than to be the main undercard fight of the biggest fight? Khan and Brook want to be superstars, ya need to get on this underfcard where the world will see you. Go to UK make some change, no one cares. You know what I'm saying?
Glad Khan isn't gonna just sit in the sidelines. If the fight happens and Khan gets a clear win, then he would have finally earned a shot at the winner of May 2nd.
If Brook fully recovered from the machete attack, he will destroy Khan not worse than Garcia did, that's for sure.
Would be a much better fight than froch groves Neanderthal vs c level bum Brook and khan are both great boxers
Will be a fantastic fight especially if the winner goes on to fight the winner of pacquio mayweather, thought he'd get an asy win over algeri and hold out for the winner. But relaly a mayweather fight wont mean much after Pacquio, this is the better root. Pity he'll never get the Mayweather fight though
