Notre Dame’s defense has spent the first three weeks looking like one of the nation’s best. Now comes the part where that reputation gets dragged into the light.
Purdue brings a very different kind of challenge to the Shillelagh Trophy matchup, and the Irish secondary will be under the microscope right away. The Boilermakers have already put up 44, 36 and 38 points in their first three games, and veteran quarterback Ryan Browne is back in the mix after hurting Notre Dame last season in South Bend. With the Irish also dealing with injuries in the back end, this feels like the first real stress test for a unit that has been rolling.
The numbers on Notre Dame’s defense are already loud. The Irish sit inside the top 10 nationally in scoring defense at No. 4, rush defense at No. 6, total defense at No. 3, turnovers gained at No. 4 and passing touchdowns allowed at No.
- But Purdue is bringing an offense that changes the picture.
The Boilermakers rank third in the country in passing yards per game, 13th in yards per attempt, 30th in passing touchdowns, 16th in passer rating and have thrown just one interception in 2026. There’s no hiding from what this game is asking of Notre Dame’s secondary.
That puts a spotlight on defensive coordinator Chris Ash’s group, especially with the Irish missing key pieces at safety. Junior Brauntae Johnson has already been out since the Wisconsin opener, and senior Luke Talich was announced as OUT for this week’s game. That leaves senior captain Adon Shuler in a major role on the back end, helping keep freshman Joey O’Brien and sophomore Ethan Long in the right spots.
The pass rush has a chance to make life easier on everyone behind it. Notre Dame’s defensive line has already played at a high level, and this matchup gives it a chance to show up in a louder way. Defensive ends Boubacar Traore and Bryce Young are positioned to be major factors, while junior defensive tackle Tionne Gray comes off the first sack of his career against Michigan State and former Pitt transfer Francis Brewu also has a chance to make noise inside.
One of the biggest individual matchups comes with Christian Gray in the nickel. Purdue’s passing game flows heavily through the slot, where Assad Waseem and Xavier Townsend have been the main targets.
Those two have combined for 49 targets, 39 catches, 588 receiving yards and three touchdowns. Gray hasn’t been tested much yet this season, but that changes now.
The nickel spot got hit a couple of times in this game a year ago, and Gray has a chance to flip that script.
On the edge, Bryce Young draws another matchup worth watching against Purdue left tackle Nuku Mafi. Mafi has allowed the most pressures along the Boilermakers’ offensive line, while Young has been one of Notre Dame’s best defensive linemen through three games. At 6-6 and 260 pounds, Young has the size and athletic edge over the 6-4, 325-pound Mafi, and he should have opportunities to add to both his sack total and his tackles for loss.
And then there’s Joey O’Brien. Notre Dame does not often lean on a true freshman on defense unless injuries force the issue, but that is where the Irish are now.
The 6-5, 200-pound Pennsylvania native, one of the highest-ranked recruits in the 2026 class, is set for a much bigger role than the short spurts he has seen so far. The last two true freshmen to start in the secondary because of injury worked out pretty well - Benjamin Morrison in 2022 and Leonard Moore in 2024.
O’Brien isn’t being placed in that company, but the confidence in what he can do is clearly there.

Notre Dame Rolled Purdue But One Offensive Concern Still Lingers
Notre Dame took care of Purdue in convincing fashion, racing to a 35-0 halftime lead and turning what could have been a tricky in-state matchup into a comfortable blowout. CJ Carr did his part with three touchdown passes, and the offense had the kind of depth that showed up in the second half as well, with Noah Grubbs and Matt Jeffery each throwing their first career touchdown passes.
Still, the clean final score did not hide every issue for the Irish. The running game never really got rolling, and Carr had enough accuracy hiccups to leave a little room for concern even in a game that was never in doubt. For a team that wants to keep building momentum, those are the kinds of details that tend to matter once the competition gets sharper. [Read more 🡒]

Notre Dame's Defense Just Changed How The Rest Of The Schedule Feels
Notre Dames defense spent the first half against Purdue making the rest of the schedule look a lot different. The Irish shut out the Boilermakers over those first two quarters and kept them bottled up with a pass rush that came from everywhere, turning pressure into sacks and turnovers while the offense spent its time benefiting from short fields and momentum.
Bryce Young was at the center of it, finishing the half with two sacks and a forced fumble that was returned for a touchdown, and true freshman Joey OBrien added a sack of his own to the mix. Purdue managed only 78 passing yards and 12 rushing yards before halftime, the kind of total that suggests Notre Dames defense is not just playing well, but capable of making an opponents entire game plan collapse.
