I dont know anyone who would think JMM vs Canelo is a good idea. JMM lack of size and strength against mayweather was clear enough. JMM might have the better skills, experience etc but he wouldnt keep Canelo off him for 12 rounds. He would be overwhelmed and stopped and he doesnt need to lower himself to that.

Anyway canelo vs Rhodes is a completely different fight than against Hatton, he could be taking him lightly and Rhodes is no mug. Alvarez would be wise to concentrate 100% on the task at hand.
