Roach: 'Khan was KO'd cold by Pac in sparring 3-4 times'

In fairness to Amir, he's braver than he should be with his chin...
He took on Maidana against all advice and managed to just about s****e through....

He probably thinks (rightly) that Pac's power has significantly lessened since their days together at the Wild Card gym and he probably believes he can beat him now....

In fact, the playing field is alot more level than a fight between them would have been several years back. I think it's a great fight should it happen.....but one would have to assume Pac still has enough pop to exploit Kahn's weak spot.
