Point #2 first. A lot of people keep saying, "Louisville is horrible" based on 2018. Well, that was 2018. Teams can and do change dramatically from one year to the next. In ND history, look at 1963 vs. 1964 when Ara coached his first year. Time will tell how good Louisville 2019 is, but they're not that talentless. Their Rivals recruiting rankings 2016-18 are 36, 29 and 31. Not elite but far from bottom-feeders.
To point #1, it sure looked like the coaches made a calculated decision that Louisville could be defeated by running a vanilla offense and not throwing deep. I would wager the same will happen vs. New Mexico. Look for the playbook to be opened vs. Georgia.
If I did have a point #3, it's that we really don't have a firm idea of what this team will be. The LBs were slow both in foot speed and recognition, so that's a problem. Book had some problems, to be sure. But to put a positive spin on this, we have two games to iron out the problems. I don't think it's a done deal that UGA will put a whipping on ND. They beat Vandy by 24 on the road and ND won by 18, so the outcomes were somewhat similar.
