Froch by a good stretch. Khan is young, and if he wins his next 3-4 fights (assuming they'll all be against quality opposition, ie Maidana, Bradley or Alexander) he will have a very, very good record. However let's not forget Froch is fighting AA this weekend!! That would be a huge win, and may even look good on the record as a defeat (depending on the manner of course). Ultimately, if both fighters win they're next 2-3 fights, against quality opponents, Froch still takes it. It'll be years before Khan closes the gap.
