Hunter Smiles: I've Seen Pacquiao-Khan Sparring Tapes

"Amir would be a tough out for Manny Pacquiao and with his energy level and length and speed, if he brought all these things together with great focus, there’s a danger that Pacquiao could lose, and lose convincingly. From a fighter stand point, I think that’s the reason why. From a political standpoint, I have no idea [why no head has been reached as of yet]. Hopefully he gets it."
