Game preview: Ohio State at USC
7:30 PM ET · Ohio State -6.5 · total 50.5 · our model: Ohio State by 7.8
Best available lines (as of 12:00 PM ET Saturday): Ohio State -6 (-110, Fanatics); USC +6.5 (-109, Caesars); Over 50.5 (-112, DraftKings); Under 51.5 (-115, FanDuel).
The total dropped from 52.5 on Sunday to 50.5 on Monday and was back up to 51.5 as of Tuesday morning. Ohio State is a 6.5-point favorite, down from 7. The Big Ten's Friday availability report lists QB Julian Sayin and RB Ja'Kobi Jackson out for Ohio State, with WR Brandon Inniss questionable and CB Jay Timmons doubtful. USC lists WR Corey Simms out and TE Mark Bowman questionable. It sits at Ohio State -6.5 as of Saturday.
Ohio State goes to the Coliseum on Saturday night without the top-ranked player in our ratings. Ryan Day said last Tuesday that QB Julian Sayin is out indefinitely with an injury to his throwing elbow, and that the Buckeyes are planning to go on without him. This Tuesday, Day still wouldn't name a starter between true freshman QB Luke Fahey and QB Tavien St. Clair, and said it's possible both play.
USC has a problem of its own. The Trojans lost 24-7 at Wisconsin and finished with minus 17 rushing yards on 25 carries, against a Wisconsin team that threw for 58 yards and still won by 17. So the biggest game on the board pairs a passing offense that just lost its quarterback with an offense that just lost the line of scrimmage.
The matchup
With Sayin, Ohio State lived through the air, throwing for 323 yards a game. WR Jeremiah Smith, second overall in our ratings, is what keeps that passing game dangerous with a new quarterback. USC's pass defense is the soft spot on its side, allowing 0.337 expected points per dropback, and national efficiency ratings have the Trojans' defense 39th nationally.
Fahey has already had one test. Sayin got hurt in the fourth quarter of the 19-15 win at Indiana on Oct 17, and Fahey finished the game. Before that, Sayin threw for 235 yards with two touchdowns and two interceptions, Smith caught a touchdown, and the Buckeyes ran 37 times for just 78 yards.
The other half is USC's passing game against the defense national efficiency ratings put first in the country. QB Jayden Maiava runs an offense averaging 304 passing yards, and USC converts 51 percent of its third downs. Ohio State allows 13.4 points a game. At Wisconsin, Maiava threw 50 times for 258 yards with two interceptions, which is what this USC offense looks like when nobody respects the run.
What decides it
With a first-time starter, Ohio State's run game has to carry more than it has all season. RB Bo Jackson had 56 yards on 18 carries at Indiana, even though the Buckeyes have not been a top-30 rushing offense this season. The opponent helps. USC allows 115 rushing yards a game and close to neutral efficiency against the run, so a simple ground plan has room to work.
USC's path runs through a line of scrimmage that just lost badly. Wisconsin stuffed 40 percent of USC's runs at or behind the line and sacked Maiava five times. Ohio State's run defense allows 93 yards a game, and its defense creates havoc on 18.2 percent of snaps. DE Kenyatta Jackson Jr. left the Indiana game hurt, and Day said he expects most, though maybe not all, of his injured defenders back after the bye. Jackson does not appear on the Big Ten's Friday availability report.
USC's offense has scored on good defenses. It put up 31 at Penn State and 27 against Oregon, and Ohio State scored 23 at Texas and 19 at Indiana in its two closest games, both with Sayin.
The market
Ohio State was a 7-point favorite last Thursday morning, dipped to 6.5 on Friday and Saturday, went back to 7 and was 6.5 again as of Tuesday morning. Day's announcement on Sayin came two days before that first number. The total has moved more, sliding from 54 on Friday to 50.5 on Monday after USC's seven-point night in Madison, then ticking back to 51.5. Ohio State sits at -6.5 as of Saturday morning, with a total of 50.5. Our model has Ohio State by 7.8 with a total of 53.7, close to the market on the side and a little higher on scoring.
Day's choice at quarterback is the thing left to learn. If Fahey or St. Clair can keep Smith involved, Ohio State's receivers against a soft USC secondary are still the mismatch of the night. If not, the game comes down to whether USC can run the ball at all against a front that has given up almost nothing on the ground.
