I'm not convinced on this 'he needs to beat Prescott to prove his chin can hold' argument.

It wouldn't convince anybody, the whole argument is silly.

If Amir rematched Prescott, he sure as well wouldn't trade with him. He'd keep on the outside and try and box his way to the win.

His plan would be to not get hit rather than test to see if his chin has improved.

If he came through it and won easily by keeping away nobody would be convinced. They would just say Prescott was shit and he was never going to hit Khan because of the speed difference and that Khan was a coward who just hit and ran.

So what is really being tested is Khan's ability to box safe, I imagine it would be a dull fight.

Michael Katsidis would be a better and more fan friendly test because he's 100% pressure. Khan would get hit on the arms, elbows, body, it would be a rough fight.
