Miami won the coin toss and elected to defer to the second half. The Tigers took the ball to open the game.
Though LSU advanced to the Miami 33-yard line, Miami pressure forced consecutive incomplete passes by Flynn and the Tigers settled for a 50-yard field goal attempt. Placekicker Chris Jackson missed the attempt to the left.
On the ensuing possession, Wright drove the Hurricanes to the LSU 4-yardline before throwing an incomplete pass in the end zone. Miami, too, settled for a field goal attempt and Jon Peattie made his 21-yard try.
Miami led, 3-0, with 8:45 to play in the first quarter.
After consecutive punts, the Tigers punt together a 10-play drive that included eight rushes and Jackson hit a 37-yard field goal to tie the game, 3-3, with 58 seconds to play in the quarter.
The field goal started the 20-consecutive points by LSU leading up to the half.

The Tigers took over at their 14-yard line, and Flynn again led the offense into Miami territory. Despite a 10-yard sack on third down, LSU made a 47-yard field goal and extended the lead to 13-3 with 4:57 left in the half.
Miami went three-and-out on the ensuing possession, allowing LSU to drive 68 yards for another touchdown. This time, Addai took a short pass from Flynn on third-and-3 from the Miami 4 and muscled into the endzone for the score.

The Tigers' dominance continued early in the second half, holding Miami to three-and-one in consecutive drives and extending the lead to 34-3 with their fifth and sixth-consecutive scoring drives.
