I love how people think Khan's chin is that **** he got caught clean on the chin by a guy with massive power and he was cught so flush cause he was careless and young since he has improved his defense big time his alot less stupid much more pathient and getting better all the time , if Khan keep's on his current track i'll go out on a limb and say Khan will be at least a 3 Weight world champ and be in the top 5 P4P for quite sometime
