X-Factor: Tobi Osunsanmi Could Be the Difference Against USC's Explosive Offense

Indiana has established itself as one of the most dominant defensive teams in college football this season, but Saturday's matchup against USC presents one of the toughest challenges yet for Curt Cignetti's defense.

The Trojans possess one of the nation's most explosive passing attacks, led by quarterback Jayden Maiava, and they'll undoubtedly test Indiana's ability to generate pressure and limit big plays.

That's why defensive lineman Tobi Osunsanmi is the biggest X-Factor for the Hoosiers this weekend.

USC enters Saturday's matchup ranked No. 10 nationally in passing offense, averaging 294.6 yards per game. The Trojans also rank No. 25 in total offense (423.8 yards per game) and No. 27 in scoring offense (32.4 points per game).

Maiava has been outstanding, throwing for 2,525 yards, 20 touchdowns and just five interceptions. He's also helped USC convert an impressive 49.53 percent of its third-down opportunities, ranking No. 12 nationally.

But Indiana has the defensive personnel to make life extremely difficult for him.

The Hoosiers rank No. 4 nationally in scoring defense, allowing just 12.4 points per game. They're also No. 5 in total defense (259.2 yards per game), No. 4 against the run (75.6 yards per game) and No. 24 against the pass (183.7 yards per game).

Perhaps most importantly, Indiana has recorded 32 sacks this season, with Osunsanmi leading the charge with 10.

That combination could be particularly problematic for USC.

The Trojans rank just No. 92 nationally in rushing offense, averaging 129.3 yards per game. Against Indiana's elite rushing defense, establishing a consistent ground game could prove extremely difficult.

If the Hoosiers can eliminate USC's rushing attack and force Maiava into obvious passing situations, Osunsanmi and the rest of Indiana's defensive front should have opportunities to wreak havoc.

The battle on third down will be especially important.

While USC ranks No. 12 nationally in third-down conversions, Indiana ranks No. 21 in third-down defense, allowing opponents to convert just 31.6 percent of their opportunities.

Consistent pressure from Osunsanmi could be the difference between USC extending drives and Indiana getting off the field.

With the Hoosiers favored by 7.5 points, limiting explosive plays and creating negative plays will be essential.

Indiana doesn't necessarily need Osunsanmi to record multiple sacks to make an impact. Simply disrupting Maiava's timing, forcing hurried throws and collapsing the pocket could completely change USC's offensive approach.

If Osunsanmi delivers another dominant performance, Indiana should have an excellent opportunity to control the game and secure another important victory.
