Source:[14] LSU won the coin toss, and deferred possession to the second half, giving Clemson the opening kickoff.

On this drive, the LSU offense moved the ball seventy yards in just 4 plays, capped by a long Joe Burrow pass to wide receiver Ja'Marr Chase, tying the game at seven with 2:20 remaining in the opening quarter.

LSU responded with a quick drive of their own, scoring in five plays to narrow the lead to three on a touchdown run by Burrow.

Joe Burrow and the LSU offense continued to build their momentum with their third consecutive touchdown drive of 75-plus yards to increase the lead to 11, 28–17, on a pass to Thaddeus Moss, heading into halftime.

For the first time in nearly an entire quarter, the Clemson offense found the end zone, as Travis Etienne capped a 6 play drive with his first touchdown of the day.

Trevor Lawrence completed a pass to Amari Rodgers for the two-point conversion, cutting the LSU lead to three points.

On the fifth play of LSU's ensuing drive, Clemson starting middle linebacker James Skalski was ejected from the game for a targeting penalty; LSU scored on the next play on a touchdown pass from Burrow to Moss (one that gave Burrow sole possession of the FBS record for touchdown passes in a season with 59)[17] to increase their lead to ten.

[15][16] LSU came out firing in the fourth quarter; they scored for just the second time this half on a Joe Burrow pass to Terrace Marshall Jr., his first receiving touchdown of the contest.

However, three plays later, Trevor Lawrence fumbled at the end of his rush; it was recovered by LSU's Derek Stingley Jr. with 3:53 to go.

LSU was able to run the remaining time off the clock and finish the season as undefeated national champions, becoming the second 15–0 team in the modern era.
