The start of the college football season saw an exciting penultimate entry on Sunday between No. 12 LSU and No. 23 USC in the Modelo Vegas Kickoff Classic.

USC upset LSU, 27-20, at Las Vegas' Allegiant Stadium on a game-winning drive executed by Trojans first-year starting quarterback Miller Moss — putting a cherry on top of what was a thrilling opening weekend of college football.

USC running back Woody Marks was the one who scored the winning touchdown, which came on a 13-yard carry up the middle with seconds left in the fourth quarter. Marks' touchdown was set up by a 20-yard reception from Kyron Hudson and a 15-yard targeting penalty on LSU's safety Jardin Gilbert.

Moss completed 27 of 36 passes for 378 yards and one touchdown. His counterpart, LSU starting quarterback Garrett Nussmeier, finished 29 of 38 for 304 yards and two touchdowns.

The 27-20 loss for LSU marks the third consecutive season it will open up the season 0-1 under Brian Kelly. The Tigers have not won their season opener since 2019, then coached by Ed Orgeron.

USC turns it over on downs

The big play on the drive came on a third-and-10 at the USC 35-yard line when Moss connected in the middle of the field with tight end Kyle Ford for a 41-yard reception. Ford broke late on the play and showed off some shiftiness after making the catch, resulting in a big play for the Trojans.

LSU also punts

Garrett Nussmeier's pass to CJ Daniels comes up short of the first down, resulting in a three-and-out for LSU to begin the half as well. Both team's offenses looking to regain their momentum from before halftime. USC takes over the ball at its own 23-yard line after the punt.

LSU vs USC predictions

Cory Diaz, The Lafayette Daily Advertiser: LSU 28, USC 24

"LSU's opening game will be an ugly one. Both teams are breaking in new QBs, who'll throw interceptions but it'll be Nussmeier that guides the Tigers down the field a late, go ahead score."

Bill Bender, The Sporting News: LSU 35, USC 28

"It's a battle of beleaguered defenses, and LSU is trying to avoid a loss in the season opener for the fifth straight season. The Trojans are closer to home here, and Lincoln Riley can prove the hire of defensive coordinator D'Anton Lynn right here. This is the Trojans' first matchup against an SEC opponent since the 52-6 loss to Alabama at Jerry World on Sept. 3, 2016 – a game now best-known for USC's ill-fated entrance to the field. Garrett Nussmeier delivers in the clutch for the Tigers in a back-and-forth thriller that Brian Kelly is now accustomed to."
