Auburn isn’t quite sure which LSU quarterback it will be facing this weekend. Myles Brennan missed last Saturday’s game against South Carolina due to injury, which led to a strong debut for LSU true freshman TJ Finley.

Auburn head coach Gus Malzahn has watched the film on Finley, and he may know what LSU will be trying to do if Finley ends up starting for the second consecutive week.

“I was very impressed with the young guy,” Malzahn told the media on Tuesday. “They ran the football, and he made some good throws in tight coverage. The big thing is that they were able to run the football successfully with Finley at quarterback.”

On the other side of the ball, Auburn’s offense will be facing an LSU defense that has had some struggles early in the season. It’s not quite as intimidating of a defense as when Auburn took on LSU last season.

But Malzahn isn’t thinking this is going to be an easy task for his offense, and he realizes that LSU’s defense has shown signs of improvement in recent weeks.

“There’s no doubt it’s going to be a test,” Malzahn told the media. “I think they’re leading the league in sacks and they have two guys who can flat-out get after the quarterback, especially on the edge. We’re going to have to do a really good job, whether it’s scheme or whether it’s situational. When they pin their ears back and they know it’s pass, they’re very effective and impressive watching them on film. …

“I think you’ve seen that their defense is fine. They’re better each week. They do have a bunch of young guys, new guys, so just trying to get that experience, but they’ve seen that the last couple weeks, they’ve improved. We’ll see what their plan is, but they definitely have improved.”

Auburn and LSU are set to kick off on Saturday at Jordan-Hare Stadium at 3:30 p.m. ET on CBS.
