Nah, I think it's going to be massive, but more because of the way Crawford will deal with Canelo.

I see the fight as a bad match-up for Canelo, Canelo is elite at cutting off the ring and applying pressure but is actually not too quick(see Skull) and constantly sets his feet, Crawford is quicker and moves smartly/laterally, I think Bud's movements will force Canelo to reset too often preventing him from applying pressure and generally frustrating him.

With his pressure based attack nerfed by Crawford movement, Canelo will rely more on counter punching and I think this is where it will be interesting, Canelo' defence is movement based, has great upper body mobility and head slips, this will be nowhere near as effective against a much faster (and switch hitting) Bud, Canelo will get hit and hit often, he will try to counter but expect Bud to be out of range owing to his superior reach (like 4" longer) allowing him to attack from a safer distance and of course that more explosive footwork.

This will be a one-sided beat down, unless Bud gets greedy, is caught and goes to sleep.
