I just don't see it. Will be interesting to see the differences in speed but you'll only really get that once they are in the ring together. To the eye Canelo looks slower but he is obviously fighting smaller guys who are all naturally quicker.
Do you remember Canelo wiping Khan out - it would be a big shock if we did not see Canelo glued to the canvas in a similar fashion.
Usyk should be actively calling this after he deals with AJ. I have a feeling Eddie was just blowing smoke up Canelo's rear end to get people talking. Canelo is not stupid he would have more chance of beating AJ than Usyk. He could come in at 190lbs and beat a 240lbs AJ if he has the chin to take a shot from a HW. But i have a feeling we would be hearing Canelo claiming 'you want payday ya ya ya ya'
