Mack Brown definitely scapegoated him, but that doesn't mean his system isn't garbage. It caught ND by surprise in 2017 in a big way and it's worked plenty of other times. But as others have said, you can't keep playing that same note over and over. If we're going to get anywhere next year at all, Manny neeeds to put his ego to the side and get a strong DC. I'm hoping that the humiliation of this game and the concern about face Bama to start next season will force him to do that.
Also ND in 2017 had a QB that was terribly inaccurate. I mean really really inaccurate. That plus the environment created a lot of what we saw that night from mannys D. JMO
