EA Rep please answer

Why in certain games does the Ai on an opposing team become unstoppable. For example an opponents d line gets super wins 90 percent of the time? It’s not due to player ranking or abilities because I have eternals on my o line with all the necessary abilities. Certain games though it seems the Ai on the other side is simply far superior. Also shows up in coverage where their Ai defenders are like super glue and knock everything out and mine are caught standing still at times? It would be one thing if it was every other play but it’s pretty obvious when a games Ai is so stacked towards an opponent
