Barry Odom stood at the lectern in Pasadena Saturday night and said he was "very disappointed in our run defense. There's no way in the world you can give up what we did." On third down, he said, "If we don't get that fixed, we have no chance defensively." Then a reporter asked whether Purdue would change its defensive play-caller, and Odom would not answer. It "would be premature for me to talk about that right now," he said, adding that Purdue has "a lot of decisions to make and a lot of areas to fix in short order." No change was announced. That is the state of things three days before the Boilermakers host No. 3 Notre Dame, and it followed a 52-38 loss at UCLA in which Purdue's defense allowed 645 yards, 369 of them rushing, and let the Bruins convert 11 of 14 third downs without forcing a single turnover.
Kevin Kane is the man whose job title that question concerns. He came back to Purdue last December as defensive coordinator and linebackers coach after a season at Minnesota, returning to a defense he had already coordinated in 2023 and 2024. He was supposed to be the familiar hand steadying a unit rebuilt almost entirely through the portal. Instead his defense allowed 52 points to UCLA, and his head coach won't say in public whether he'll be calling the plays Saturday. A Sports Illustrated/Yahoo Sports columnist has already argued that Odom should take the defense over himself, which is one writer's opinion rather than anything the staff has signaled. Odom's non-answer is the actual news.
The offense is not the thing that broke
Here's what makes this week uncomfortable rather than just bleak. Purdue was winning that game. The Boilermakers trailed 21-7 after a quarter, outscored UCLA 14-3 in the second, and took a 28-24 lead in the third quarter on a George Burhenn touchdown catch. From there UCLA scored 28 of the game's last 38 points. Ryan Browne went 19-of-30 for a career-high 378 yards and three touchdowns, his third straight 300-yard game, with Xavier Townsend catching six balls for 162 yards and two scores and Asaad Waseem adding eight for 149. Purdue is averaging 489 yards a game and has scored 44, 36 (in double overtime against Wake Forest) and 38 through its first three games this season.
So the thing Purdue fans spent two years begging for has arrived, and it has not produced a win. Three turnovers did real damage at UCLA. Travis Terrell Jr. fumbled on his first carry and UCLA scored, Waseem fumbled on the first play of a third-quarter possession and UCLA scored again, and Browne threw an interception near the goal line with 5:46 left in the fourth quarter. Odom said the margin for error is "slim to none." Against Notre Dame it is thinner than that.
What Saturday can actually show you
Kickoff is 2 p.m. ET at Ross-Ade Stadium on Peacock, and the simulation gives Purdue a 2.4 percent chance. That number is not a typo and it is not worth arguing with. Notre Dame leads the series 61-26-2, has won the last 10 meetings, and plays Purdue for the Shillelagh Trophy. The last time the Irish came to Ross-Ade, in September 2024, they led 42-0 at halftime and won 66-7, the worst loss in Purdue's 137-year history. Nobody needs to relive that to know what a bad Saturday looks like.
So start with Notre Dame's first third down. Does Purdue get off the field? Does the call arrive on time? Seven of UCLA's conversions needed seven or more yards, including third-and-10, third-and-12 and third-and-15. That is not a talent gap. That is a defense guessing wrong. If those situations look different Saturday, something changed in the meeting rooms this week whether or not anyone announces it.
Two other things will tell you how long Purdue can stay in it. Fame Ijeboi carried 17 times for 47 yards at UCLA, about 2.8 a pop, after Odom said he was "a little bit limited throughout the week", and with starting left tackle Joey Tanona still not having played this season because of an ankle injury, that is the specific reason Purdue may not be able to grind out possessions and keep a stressed defense on the sideline. A one-dimensional offense against Notre Dame means a lot of Irish snaps. And Purdue cut its penalty count to six for 45 yards, but an illegal-formation flag still wiped a touchdown off the board. Points given back matter more, not less, when you are a four-touchdown underdog.
Purdue is 1-2 with a 19-game Big Ten losing streak, and Notre Dame is a non-conference opponent, so nothing Saturday touches that streak either way. What's available is narrower and still worth your afternoon, Browne connecting with Townsend and Waseem against the best secondary he'll see, and a defense that has been publicly called out getting a chance to answer in front of its own crowd. A competitive first half would be genuine evidence. Hanging around into the fourth quarter would be the best Purdue day since 2022.
