In this "David and Goliath" Week 4 college football battle, one team has everything to lose, while the other has everything to gain.
After beginning the 2025 campaign with losses to Miami and Texas A&M, Notre Dame has seen its margin for error (in terms of reaching the College Football Playoff) reach near zero. A win over Purdue is exactly what the Fighting Irish need to get their season back on track.

The Boilermakers, meanwhile, enter this contest as massive underdogs with the potential to do serious damage to Notre Dame's postseason hopes. Purdue, after starting the season with wins over Ball State and Southern Illinois, suffered its first defeat last weekend on the road at USC.
