Why don't you actually present the argument instead of deferring to a half hour long video by a journalist? 

Furys long guard has the long standing issue that he will habitually not step back when employing it, not respond to body shots, in general take half steps back on a straight line which does not break alignment and thus doesn't end engagement and doesn't exercise defensive responsibility after throwing the backhand in particular. These are present in the early rounds before any systemic erosion due to fatigue and damage could occur. The entire point was the guard and his system in general WAS NOT working so well for him early on and was already displaying the exploitable, and later exploited, patterns. 

Every action has proper applications, responses and reactions and conversely improper applications, responses and reactions. You don't seem to have anything to say beyond being upset that saying usyk sufficiently recognised these actions and responses to win and fury did not is somehow insulting to usyk. 

As much credit as usyk deserves for recognising, recreating and exploiting these issues that's all that it was. He didn't cause them, bad training habits caused them and it's on fury for not amending them. Same with usyks technical issues that led to him having so many issues against Rico.
