I think Khan is trying to make fights that have little risk should he lose. Chasing Mayweather and Pacquiao, he knew if he lost those fights (which was the most likely outcome), then he would still earn the money but not really lose much credibility because of who he was fighting. I think the same applies to this fight with Canelo, he will go in as a big underdog and, in my opinion, will lose very comfortably. I think he will start off on the outside and stay away from Canelo, but eventually will get tagged and get drawn into a fight which is where Canelo will overwhelm him. He will come out of this fight though with a lot of his reputation still intact because he is going up in weights and expected to lose.
On the other hand, he could have taken more money and fought Brook, but if he lost that one to a domestic rival after all the talk, then his reputation would be shot and he would have to look at giving up or starting a rebuilding job bigger than after the Garcia knockout
