1. What we learned

Auburn has all the marks of a seasoned, confident College Football Playoff contender. LSU does not. Not by a long shot. A painful, sobering 41-7 loss that is the program’s worst since losing to Auburn by the same score in 1999 was without hardly any redeeming value for LSU. All the numbers were bad: margin of defeat, points allowed, yards allowed, even the fact LSU was 0-for-13 on third-down conversions. That LSU lost by such a huge margin was made more troubling by the fact that the Tigers didn’t turn the ball over.

2. Trending now

LSU’s quarterback situation. Again. Freshman Brandon Harris got his first career start, and immediately his helmet started spinning. He left the game having completed just 3 of 14 passes for 58 yards, 52 of those on one play. Anthony Jennings returned and did a solid job despite having been benched a week earlier, but he didn’t lead LSU to any points. Where LSU goes from here at QB is debatable, but it looks like Les Miles is stuck with exactly what he didn’t want: a two-QB system in which neither can win the job, only lose it.

3. Final thoughts

Patience is the watchword for LSU this season. But a loss of this magnitude, which ties the worst defeat LSU has had since before it began its unprecedented run of success in 2000, is alarming. LSU is rebuilding in a year when the SEC West appears to never have been better. But no one is going to feel sorry for its young quarterbacks or porous defense. If LSU is going to find any respectability this season, it’s going to have to fight for it. We will see if the Tigers have that fight in them.
