Duke vs. Illinois Prediction, Spread, Over/Under for Week 2

The Blue Devils are coming off their fourth straight winning season, something that seemed nearly impossible at a basketball school. However, head coach Manny Diaz needed to replace his star QB Darian Mensah, who transferred to Miami in the offseason.

Diaz brought in QB Walker Eget from San Jose State, who is coming off a 3,000-yard passing season in 2025. In his Blue Devils debut, Eget completed 50.0% of his passes and was held to 131 passing yards. Last season, Eget posted a pair of 450+ yard performances against Stanford and Hawaii.

QB Katin Houser compiled an efficient 13-of-17 passing for 182 yards and 3 TDs in his Fighting Illini debut. The former East Carolina signal-caller put together an EPA of 15.72 and 10.71 yards per pass. 

Illinois improved to 20-7 since the start of 2024, which has been a nice turnaround under head coach Bret Bielema after winning 18 games in his first three seasons.

The Fighting Illini routed the Blue Devils last season in Durham, 45-19, as two-point favorites. The yardage numbers were nearly identical, with Illinois outgaining Duke 438-436. However, the difference was 6 turnovers by the Blue Devils, including 4 lost fumbles.
