Canelo fought like a robot. He had no killing instinct and he was hit easily. His youth, stamina, and speed helped him to get through those tough fights. He needs to work on his defense since fighters who have poor defense will usually have health problems in the long run. However, I just said what I saw. You may not agree with me.
It's coming along. His guard his tight, and his judge of distance is functional. More upper body movement and less stiffness would do him good.
I know that Alvarez is a great warrior and he loves trading punches but you can see what's happening to fighters who have poor defence like Margarito, Pavlik, and Williams, can't you? BTW, WTF is happening up there?
