Auburn QB Nick Marshall vs. LSU’s linebackers

Mississippi State’s Dak Prescott provided a blueprint for piercing the LSU defense. If there’s one quarterback in the Southeastern Conference who has similar mobility to Prescott’s, it’s Marshall. He has thrived in the run game early in possessions this year: The senior has 39 carries for 289 yards and two touchdowns on first and second down. Two weeks ago, Prescott made plays with his legs. LSU’s linebackers should have their hands full in Jordan-Hare Stadium.

Auburn S Jermaine Whitehead vs. LSU QB Brandon Harris

It’s official: Harris, LSU’s true freshman quarterback, will start against Auburn. That said, outside of a Mississippi State defense flooded with backups, Harris has yet to face the best that the SEC has to offer. Auburn’s pass defense ranks No. 7 in the conference, allowing 222.5 yards per game. Patrolling center field Saturday night will be Whitehead, a senior who has two interceptions, including one he returned for a touchdown. Harris will have to keep his eyes peeled.

Auburn’s offensive line vs. LSU’s defensive tackles

LSU is running out of defensive tackles. With the loss of junior Quentin Thomas and with redshirt freshman Frank Herron nicked up, the Tigers will rely on sophomore Christian LaCouture to carry the young middle of the line. Auburn’s offensive linemen have been a force, allowing two sacks in four games.

Say what?

“My first hostile environment that I remember was a baseball diamond in what would be southern Ohio, OK? That was a very hostile environment. I can tell you as a sophomore in wrestling, we went to Mentor (High School), and they had to walk us out of the gym into the bus, onto the buses.”

By the numbers

2 -- Defensive touchdowns LSU has in 2014. The defense has allowed just two passing touchdowns.

7 -- Touchdown scoring drives led by freshman Brandon Harris against New Mexico State.

99 -- Career wins Les Miles has at LSU. With one more victory, Miles, in his 10th season in Baton Rouge, would become the second LSU coach to reach the century mark, joining Charles McClendon (137 in 18 years).
