To be honest Khan has suppassed this loss and proven alot of people including me wrong.

but saying all that it is still unfinished buisness and he should rematch him to just show it was a bad night at the office.

Lennox Lewis avenged all his losses and no one says yeah he was good but he did get KO'd by etc etc

so from a legacy point of view why not it would still sell quite well at this point in time IMHO
