Ok I'll give you that but that was not a prime Zab by any means and Khan himself has declined a lot since that fight. Whatever chance he ever had of beating the likes of Bradley is long gone now imo.
Well Khan has never had a problem against those who can't hurt him. All depends if you think Bradley's pillow punches can test Khan's wobbly chin.
Khan has looked fine out boxing crude guys the best boxer he has fought was either a way past prime Judah or Malignaggi. Bradley has proven himself a level above anyone else Khan has fought. Bradley may not have the power to KO Khan easily, Khan has more weaknesses other than a poor chin. He's predictable, cannot counter punch and lacks ring intelligence. But Khan is no doubt insanely fast and athletic. I see Khan giving Bradley problems but he may not get the chance to face him. Ironically the fight Khan wants the most against Mayweather could go to Bradley who is now clearly more deserving.
