Khan was an excellent boxer, is record is outstanding, but he seemed like he had issues too. He's fast, technical, good combinations, and strong, but he gets over confident and cant bring himself back when he gets hurt. I don't believe the glass chin thing, The prescott thing over confidence and he got caught cold. He was doing well against Garcia and Canello until he got bombed. No shame in losing to those guys. I think i remember the Peterson fight, and the problem was that he wasn't timing his jab early enough. Peterson would bundle forward, tie him up and frustrate him, then Khan ended up getting tired wrestling him. It was a shitty fight.
I actually thought he would have given Mayweather a really bad night. I think without having to worry about any big shots coming in, he would have been able to point fight him to a win.
