Trout made a good point which is Canelo has never really been hit by a true junior middleweight, which is true.
The other thing that worries me about Canelo is he doesn't really use his jab. He throws good combos but against a boxer if you don't use your jab to get inside or set up shots it could be a long night. Look at Donaire against Rigondeaux, he completely abandoned his jab. Not to say Trout is Rigondeaux status just saying.
