The first official Saturday of the 2024 college football season is in the books.

Now it's time for LSU football to take the stage with the marquee game of the day on Sunday. The No. 12-ranked Tigers take on No. 23 USC in what is now an SEC-Big Ten matchup following the latest round of college football realignment.

LSU and USC will face off on Sunday inside Las Vegas' Allegiant Stadium at 6:30 p.m. CT. Both teams will be breaking in new starting quarterbacks from last season after the Trojans' Caleb Williams and Tigers' Jayden Daniels went with the first two picks of the 2024 NFL draft, respectively.

Garrett Nussmeier takes the reins at QB for Brian Kelly and the Tigers, while Miller Moss gets the start for Lincoln Riley and No. 23 USC.

The top-25 showdown could have major ramifications at the end of the season with the newly expanded 12-team College Football Playoff. The Tigers are coming off a 10-3 season and are 20-7 in two seasons under Kelly. Meanwhile, USC is coming off a disappointing 8-5 season and is 19-8 in two years under Riley.

Sunday's matchup between the Tigers and Trojans is the third all-time matchup between the two stories programs and the first one since 1984, when LSU emerged victorious in Los Angeles.

LSU vs USC predictions, picks, odds

Cory Diaz, Daily Advertiser: LSU 24, USC 21

"There's won't be as many points as most Vegas lines are predicting as this will be an ugly game with both teams committing mistakes with turnovers. LSU gets just enough stops on defense to edge out USC for its first season-opening win since 2019."

Brad Crawford, 247Sports: LSU 34, USC 27

"This could be the game of the weekend, folks. And it gets prime-time billing in its own designated spot in Las Vegas. Brian Kelly has lost back-to-back season openers with the Tigers and this time around, sports a new-look defense under former Missouri coordinator Blake Baker. He's got a first-year starting quarterback as well with Garrett Nussmeier taking over for Jayden Daniels. Will Lincoln Riley prove doubters wrong with improvements across the board or is USC in for a long season before Big Ten play begins? This could be a one-score game with more physical team prevailing."

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."
