I hope you're wrong about that last part. The way LSU has won games this year is unsustainable. I'll point you to the 2012 Florida Gators, who had a very nice defense that allowed them to rack up a bunch of close wins and have a great season - getting to a 11-1 regular season and #4 ranking before a bowl loss. Anyone who watched this team knew that they couldn't keep winning with an offense that bad - and they didn't. They regressed to the mean and went 4-8 the very next year.
Yes to Louisville - but it was prior to Lamar Jackson getting there. I think it was Teddy Bridgewater. (The Louisville Cardinals get better QBs than LSU - which should not be possible).
In the SEC LSU is last in pass offense at 6.7 yards per attempt. Meanwhile Arkansas and aTm are 12 & 14 in pass defense, 8.3 & 8.5 ypa respectively. Look for LSU’s passing attack to vastly improve over these two games.
