Washington and USC meet Saturday night in Los Angeles with both teams trying to recover from their first conference loss. Washington enters 3-1 after a 27-24 home loss to Minnesota, while No. 18 USC is 4-1 after Oregon beat the Trojans 41-27. The matchup sets up as a battle between Washington’s strong season-long defensive numbers and a USC offense that has been one of the most productive units in the country.
Why Our Model Sees Value:

“The pricing appears to lean too heavily on Washington’s 16.75 points allowed per game and its lackluster offensive showing against Minnesota. USC has enough passing efficiency to push Washington into a faster game, while the Trojans’ own defense has given opponents opportunities to attack through the air.”
ATS Projections Favor the Over
Polymarket had this matchup at a 58.5 total Wednesday, and its current main total has moved to 57.5. Over 57.5 is priced at 51¢, while USC -9.5 is 50¢. The total has stayed relatively high even after Washington produced only 24 points against Minnesota. My projection lands near 62 total points, with USC around 34 and Washington around 28.
Why Take the Over?
The strongest reason to favor the over is matchup-specific. USC is averaging 39.8 points and 489.4 yards per game, including 325 passing yards per game. Washington is averaging 288.5 passing yards itself, and USC is allowing 236.2 passing yards per game. USC has also played 4 games that finished with at least 68 combined points.

USC is 1-1 in Big Ten play, and Washington is 0-1, so another loss would leave either side with substantial ground to recover in the Big Ten conference championship race. USC remains No. 18, but its 41-27 loss to Oregon exposed defensive issues that have appeared several times this season. Washington’s loss to Minnesota was especially costly because it came at home and included just 40 rushing yards and 1 conversion on 10 third downs.
Jayden Maiava is the central matchup problem for Washington. He has completed 70.1% of his passes for 1,499 yards, 14 touchdowns and 2 interceptions through 5 games. USC averages 6.9 yards per offensive play, and Maiava threw for 326 yards and 2 scores even in the loss to Oregon.
Washington has defended the pass well this season, allowing 178.8 yards per game and 6.4 yards per attempt. That makes early-down pressure important. If the Huskies let Maiava stay comfortable, USC can create scoring chances without relying on long drives.
Demond Williams Jr. gives Washington a realistic path to keeping pace and is a reason that our Washington vs USC prediction points to the over. He has thrown for 1,129 yards while completing 69.3% of his passes, and Washington averages 8.2 yards per pass attempt. The problem is protection. Minnesota sacked Williams 7 times, held Washington to 40 rushing yards and forced 2 interceptions.
USC’s defense is allowing 354.8 yards and 26.4 points per game. Oregon produced 504 total yards last week, while USC has surrendered 30 or more points in 3 of its 5 games. If Washington protects Williams better than it did against Minnesota, the Huskies should find opportunities against a USC pass defense allowing 236.2 yards per game.
USC should have the easier path to points because of its passing efficiency, home field, and ability to sustain drives. Washington’s chance to stay close depends on avoiding negative plays and converting its passing production into touchdowns. That combination favors a higher-scoring game more than a side prediction. A score in the 34-28 range fits the statistical background of both teams and clears 58.5 without requiring an extreme offensive performance from either team.
