Good fight for Khan. If he can beat Maidana, and I think he can, then for me this undoes his loss to prescott. Khan will always have a weak chin, but in Maidana I see a guy who has the big power punches that prescott had but is far better in every other area, so a win here would prove for me that Khan belongs alongside the likes of Alexander and Bradley.
As for the fight itself, Khan will play this one close to the game plan, and win a wide UD or late stoppage. I don't think that Roach is going to let Khan take any risks in this fight, especially not early on.
