Yeah that is true but what about the old Tyson adage of "everyone has a plan until they get punched in the mouth". I doubt Chimaev made a conscious decision to fight like a moron, I'm guessing he didn't really react well to an opponent fighting back for the first time, and an opponent with a solid skillset. His fight IQ is not the best, and he was less calm and more easily thrown/flustered than I expected.
Magny is not as good as Burns you're right, but against his most experienced and wily foe yet, Shavkat showed excellent composure, patience, IQ etc.
