The Notre Dame defense was a much-maligned unit coming into their matchup with the No. 1 team and No. 1 offense in the country last night, and for good reason. Since the start of 2025, they didn't rise to the occasion against the Hurricanes last season, Texas A&M last season or against BYU this October. What would be in store when Miami traveled up to South Bend? We didn't know. All we did know was that this defense needed to play better in the biggest regular season game of Marcus Freeman's tenure and they did. 

With some key players sitting on the sideline with injuries, this unit stepped up, started fast and got that stop in the final moments they desperately needed. Defensive coordinator Chris Ash, Freeman and the rest of the defensive staff didn't play around this week in preparation and got this unit prepared despite being down two starting defensive tackles, their starting middle linebacker, a starting cornerback and starting safety. Here are my key takeaways from the Notre Dame defense against the No. 1 ranked Hurricanes. 

We always talk about starting fast one the offensive side of the ball. Last night, the Fighting Irish defense started off fast and didn't let up in the first 30 minutes of play. For the first time since the national title game against Indiana, Miami was held scoreless in the first quarter and for the first time since October of 2023, the Hurricanes were held to just three total points in the first half. Notre Dame won the battle situationally in the first half, preventing Miami from converting a single third down (0-6) and held them to just 145 total yards of offense. 

Miami's push in the second half proved to not be enough, but it was the 24-3 cushion they had prevented their comeback from being the dagger it could have been. This was the most dominant half of football we've seen from an Ash-led defense against a top-level team since his arrival in South Bend. If this is a preview of things to come, this defense is going to to be one of the best in the country come time for the College Football Playoffs. 

Through the first four games of the season, the Notre Dame pass rush was one of the best in the country. To start the season, the Fighting Irish defensive line generated 52 total pressures and and 20 hits plus sacks on the quarterback according to PFF. In their last four outings prior to Miami, they only recorded 23 pressures and seven hits plus sacks on the quarterback. That level of production would not cut it against this high-powered Miami offense and the entire defense rose to the occasion against the Hurricanes 

According to PFF, Notre Dame finished the night with 34 total pressures including six hits plus sacks on quarterback Darian Mensah. Defensive end Bryce Young led the charge with eight total pressures, but senior Boubacar Traore was right behind him with seven total pressures. Defensive tackle Armel Mukam had his most productive game in a Fighting Irish uniform and totaled five pressures while both linebackers Kyngstonn Viliamu-Asa and Jaylen Sneed combined for eight. This was an outstanding performance from the Notre Dame pass rush and it prevented the Miami offense from putting up the big points we're so used to seeing. 

With the level of injuries Notre Dame entered the game with, and endured during the matchup with players exiting for a couple of series, the depth on this unit had to shine. The 'next man in' mentality is very real and we've seen it be a strength and a detriment to various teams from South Bend. Last night, it was a strength and players had to step up coming into this matchup and throughout the night. Viliamu-Asa walked into his first start of the season wearing the green dot, handling all coach-to-player communication and excelled. 

Cornerback Jayden Sanders was getting the biggest start of his young collegiate career and, despite some technical issues which led to some penalties, had a really strong performance. We saw some younger, more inexperienced players get in during crucial moments as well. Last night, Madden Faraimo, Sean Sevillano, Rodney Dunham, Joey O'Brien, Mark Zackery and Elijah Hughes combine to play 81 snaps and produce while they were in. The depth of the Notre Dame defense was on full display and handled their business when given the opportunity.
