Clint Moseley's first career start for Auburn was one he probably won't be able to forget - at least not until the soreness of six sacks wears off.
One week after winning over coach Gene Chizik with his second-half performance in a victory over Florida, Moseley was held to 12-of-20 passing for 145 yards and had an interception returned for a score in 19th-ranked Auburn's 45-10 loss to No. 1 LSU on Saturday.
''I have definitely never been under that kind of heat before,'' Moseley said. ''I thought Sweet Water (Ala.) in high school was bad. This is a whole different league. They really put the pressure on me and it definitely got to me a couple of times.''
So harassed was Moseley by LSU's short-handed but nonetheless formidable defense, Chizik wasn't even sure how to judge the sophomore's performance.
''It's really difficult to really assess how he did,'' Auburn coach Gene Chizik said of Moseley. ''Six sacks are unacceptable. You won't win any football games by allowing six sacks. That was an anemic job of protecting the quarterback. We have a lot of work to do and a lot of research to do to figure out how to stop the bleeding in that regard.''
After quickly falling behind 7-0 on Kenny Hilliard's 9-yard touchdown to cap LSU's first drive of the game, Auburn kept the game close for much of the first half.
Auburn was threatening to tie it at 7, but Barkevious Mingo's second sack of the game forced Auburn to settle for Cody Parkey's 42 field goal, and that was as close as it got.
Half way through the second quarter, LSU went ahead 14-3 when Jordan Jefferson spotted Rueben Randle streaking down the right sideline and released a perfect pass with two pass rushers converging on him.
Late in the quarter, Jarrett Lee lofted a third-down pass down the same right sideline that, Randle who had blown past two defenders, caught in stride for what looked like a replay of his first score.
LSU was without star cornerback Tyrann Mathieu, leading rusher Spencer Ware and defensive back Tharold Simon - all suspended one game for violating the team's drug policy.
''It just seems like no matter who goes down or who's out, we have guys who are ready to step in ... and not just to fill a spot but to go in and dominate,'' said LSU center T-Bob Hebert.
Off next week, LSU (8-0, 5-0 SEC) will be unbeaten entering its showdown at No. 2 Alabama on Nov. 5.
The Crimson Tide were playing at home Saturday night against struggling Tennessee.
The beneficiary of Ware's absence was freshman Hilliard, who scored the first two touchdowns of his career while rushing for 65 yards on only 10 carries.
Randle finished with five receptions for 106 yards. Lee was 14 of 20 for 165 yards and two touchdowns, while Jefferson completed two of three passes for 54 yards. LSU gained 174 yards on the ground.
If anyone questioned how deep LSU could really be at defensive back, it was none other than Mathieu's replacement, Ron Brooks, who made the interception and returned it 28 yards for a score that made it 42-3 only half way through the third quarter.
LSU also blitzed relentlessly, which Mingo said was part of the plan with Auburn using Moseley and periodically rotating in freshman backup Kiehl Frazier.
''They blitz a lot,'' Frazier said. ''We didn't know where they were coming from and we really didn't execute like we should have as a team.''
Auburn (5-3, 3-2) was held to 87 yards rushing, led by Michael Dyer's 60 yards. Ontario McCalebb scored Auburn's lone touchdown in the fourth quarter.
''The reality of it is we got beat in just about every phase of the game,'' Chizik said. ''They did a lot of whatever they wanted.''
All season, LSU has appeared increasingly galvanized by each potential pitfall and coach Les Miles even mentioned several weeks ago that adversity seems to strengthen his tight-knit team's resolve.
It's getting pretty hard to argue with that, considering LSU responded to its latest crisis with the most lopsided victory by either team in the 46-game history of the series. It was Auburn's worst loss since a 51-10 demolition at the hands of then-No. 1 Florida in 1996.
LSU defenders and coverage teams swarmed to the ball, delivering crushing hits that provoked collective gasps from the Death Valley crowd.
One such hit was delivered by safety Eric Reid, who jarred the ball from kickoff returner Tre Mason. LSU's Tahj Jones found the football while losing his helmet, rising in celebration with his dreadlocks aflutter at the Auburn 22.
Hilliard then more than made up for a holding penalty with a 25-yard carry, which set up his second score on a 1-yard dive to make it 35-3.
