DraftKings · as of July 8, 2026

Notre Dame defeated Purdue 56–30 to secure a comfortable win. Notre Dame covered by 1.5; Game went Over by 34.5. The market closed at Notre Dame -24.5 and the Blue Chip model made it Notre Dame -28.9 - a gap of 4.4 points toward Notre Dame, of which 3.2 points were beyond the model's measured factors. That was an information gap - the market pricing something the model does not carry - rather than a measured edge.

What are the key factors for Purdue vs Notre Dame?

Notre Dame

Offensive Explosion Led by Price and Love

Jadarian Price scored four touchdowns (three rushing, one 100-yard kickoff return) and Jeremiyah Love added 157 rushing yards and two scores, powering Notre Dame to 56 points. This balanced attack will be key against Arkansas.

Defensive Improvement in Second Half

After allowing 23 points and 286 yards in the first half, the defense tightened up, allowing only one late touchdown in the second half. The two interceptions and two sacks show progress from earlier struggles.

Resilience After 0-2 Start

Coach Freeman challenged the team to face their 0-2 record honestly, and they responded with a dominant win. This mental toughness could carry over into a tough road game at Arkansas.

Quarterback Efficiency

C.J. Carr was highly efficient, completing 10 of 12 passes for 223 yards and two touchdowns. His accuracy and decision-making will be crucial against Arkansas' defense.
