Depends how Haye fairs with the Klit's, he has already unified a division, so few steps ahead of Khan.
I can't see khan clearing out light welter in the same way in which Haye cleaned out cruiser. On the other hand the 140lb division has a deeper talent pool than the cruiserweight division that Haye conquered. Froch continues to fight the best out there in probably boxings 2nd most stacked division. If he gets another good win or two his stock would sky rocket. However, I feel as though he was somewhat found out against Dirrell and will have a tough time of it in the rest of the super six.
Depends, Haye is favourite but if roach can work on khan than he has a good 10 years in front of him.
Toss up between Haye/Khan. Khan is in a better division so i wouldn't be surprised if Haye achieved more.
