USC's recruiting momentum continued with another big addition Friday, as 2021 defensive end Colin Mobley (DeMatha HS/Hyattsville, Md.) announced his Trojans commitment.

Mobley is the second defensive lineman commit in this class for USC along with 4-star DT Jay Toia (Grace Brethren HS), who committed back in June of 2018.

He's the 12th commit overall for the Trojans in this class and the ninth since March 11, as the new defensive staff in particular has been highly productive in making an immediate impact on the recruiting trail.

We take a closer look at Mobley's commitment, including what it means for the program, a look inside the film room and scouting reports from both DeMatha HS coach Bill McGregor and Rivals analyst Adam Friedman.

USC signed three defensive linemen in the 2020 recruiting class, landing defensive tackles Jamar Sekona and Kobe Pepe and defensive end Tuli Tuipulotu.

But the position group figures to see major turnover after next season and remains an area of focus for the staff. Defensive tackles Jay Tufele and Marlon Tuipulotu could be bound for the NFL draft, veteran rotation cog Brandon Pili is entering his senior year and defensive ends Caleb Tremblay and Connor Murrphy are also entering their final years of eligibility.

Mobley and early 4-star commit Jay Toia are already in the fold of this 2021 class, but defensive line coach Vic So'oto is still eyeing some high-end targets like 5-star DEs Korey Foreman (Corona Centennial HS), J.T. Tuimoloau (Eastside Catholic HS/Bellevue, Wash.), 5-star DT Maason Smith (Terrebonne HS/Houma, La.) and 4-star DE Aaron Armitage (Blair Academy/Blairstown, N.J.), so don't expect the Trojans to be done adding talent along the defensive line.

Meanwhile, the new defensive staff now has landed three 4-star safeties (Calen Bullock, Anthony Beavers and Xamarion Gordon), along with a 4-star linebacker (Julien Simon, plus early 4-star OLB commit Ma'a Gaoteote) and Mobley (plus early commit Toia).

Not a bad start.

Overall, USC is up to No. 3 in the Rivals rankings with its 12 commits -- including eight Rivals250 prospects. That includes a pair of top-25 overall prospects on the offensive side in WR Quay Davis and QB Jake Garcia, and 4-star RB Brandon Campbell. And 3-star offensive linemen Mason Murphy and Maximus Gibbs also have a chance at ending up as 4-stars.
