BATON ROUGE, La. — Lane Kiffin’s debut at LSU went about as well as it could have, and unfortunately, it came at Dabo Swinney’s and Clemson’s expense.

No. 11 LSU (1-0) did about anything it wanted as the Bayou Bengals obliterated Clemson 51-10, marking the worst loss in Swinney’s career as a head coach. The loss also marks Clemson’s fourth consecutive loss in a season-opener and fifth in the past six seasons.

The win gives LSU a 5-1 advantage all-time in the series between the two schools, including wins in each of the last three games between the two programs.

LSU outgained Clemson 644-145. Yes, you read that right. And 71 of those yards came on one drive late in the game after LSU had started resting starters. LSU had 38 first downs to Clemson’s eight. Yes, you read that right, too. Four of those came on that same fourth-quarter drive.

Tom Allen’s defense just had no answer for Sam Leavitt, as the LSU quarterback threw for 230 yards with one touchdown, a 32-yard touchdown strike to Winston Watkins Jr. in the third quarter. Watkins led the Bayou Bengals with seven catches for 110 yards. Leavitt added another 113 yards via his legs, including touchdown runs of eight and 13 yards. He came out of the game late in the third quarter.

Running back Dilin Jones finished with 113 yards on the ground with two touchdowns.

Missed assignments, missed tackles and bad angles plagued Allen’s unit from start to finish as the Tigers (0-1) finished with just one sack, which was the only tackle for loss on the night.

After Ashton Hampton picked off a pass on the game’s second play from scrimmage, Nolan Hauser would boot a 49-yard field goal to give the Tigers an early 3-0 lead. It was all downhill after that. LSU scored on five of its next seven drives to take a commanding 31-3 lead into halftime.

The onslaught continued after the break, with LSU tacking on 13 more points in the third quarter and seven more in the fourth. Only twice did Clemson force LSU to punt.

We could go on and on about what went right for LSU, but this one was more about how dysfunctional Clemson looked. That tempo Chad Morris wanted to run on offense? Never seen. Although it is hard to run tempo when your offense can’t generate first downs.

The Tigers’ inexperience along the offensive line stood out like a sore thumb. There were breakdowns everywhere, allowing the LSU defense to make a living in the backfield. Gideon Davidson had seven carries for 20 yards, while Chris Johnson Jr. had three for -2 yards. Chris Vizzina and Tait Reynolds combined to rush for -13 yards, while Bryant Wesco had one carry for -7 yards. As a team, Clemson had zero rushing yards after three quarters. The team finished with 40 after picking up some fourth-quarter yards on the ground against backups. Jarvis Green had 20 yards on the ground, while David Eziomume scored Clemson’s only touchdown on an 11-yard run late in the game.

The offensive line woes also impacted the quarterback play. Vizzina struggled mightily, rarely having time to scan the field. He completed 10-of-16 for 83 yards before being taken out of the game late in the first half. He did not return until 10 minutes remained in the contest. Reynolds didn’t fare any better, with the freshman often looking like the rookie he is. Reynolds finished 4-of-6 for 22 yards. LSU combined to sack the two quarterbacks four times.

Clemson now goes back to the drawing board in an effort to regroup for next week’s home opener against Georgia Southern.
