Some quick thoughts on LSU’s 31-0 win over Louisiana-Monroe.

What it means: The defense is excellent, but there’s a blueprint to stop the offense. LSU allowed 93 total yards, 5 first downs and was constantly in the backfield in its second straight shutout. The secondary is among the very best in the country, and might be the best. The offense looked very vulnerable, though, and Les Miles is going to have to find some answers there.

What I liked: The freshman running backs. The Tigers’ other freshman running back, Darrel Williams, is showing a real nose for the end zone, and he probably has the best burst of any of LSU’s four regulars at running back. He’s got three TDs in the last two games after scoring two on Saturday. Fournette was the leading rusher for the second straight game and flashed the wheels he was known for in high school on his 24-yard score.

Who’s the man: The entire defense. It doesn’t matter who it is: if they can hold an opponent under 100 total yards, you know this unit is for real. They got excellent pressure on QB Pete Thomas all night and absolutely smothered ULM’s receivers and the running game. They did it all without forcing a turnover until late in the fourth.

Key plays: Les Miles’ two-RB sets. We noted this after last week’s game, but Miles has found a way to get two of his talented RBs in the backfield at once, lining one of them up close as a fullback. The Tigers scored thrice out of that type of formation against ULM, two by Williams and one by Kenny Hilliard.

What’s next: LSU heads into it’s SEC schedule riding a two-game shutout streak. Mississippi State, led by Dak Prescott, rolls into Baton Rouge next week after a blowout over South Alabama on Saturday.
