It's hard to dissect what actually happened.
Khan's always chased the money fights rather than the opponents in his skill range, the more Khan-biased fans will say he's fought the best but let's be honest he had no business sharing a ring with Canelo and Crawford back when Brook was an option then, and the W's against Judah and Malignanni emphasise the argument even more, they were fighters 10-15 years past their peak entering jobber status, and you gotta remember at that period he was calling out Pacman and Mayweather which we now is absolute insanity. There's a certain amount due for calling out the best, but I think it's become clear at this point the W's weren't in mind but the £££
As people figured out tonight, Khan knew he was blew up.. The most amount of training he did was for Ant and Dec not in a ring and it showed. He's earned millions from it and fair play but Brook was there for the taking, this is a psychologically and physically broken man who bailed out the last 2 fights from a single skirmish protecting his health from the eye injury and Khan simply didn't want it.
