Even the most ardent supporters of Duke football probably looked at the schedule in the preseason and penciled in the Week 2 road trip to Illinois as a loss. But after one week of action, there's legitimate reason for optimism that Manny Diaz can lead his Blue Devils to a surprising road upset.
Oddsmakers view this game as closer than many might think. The spread has hovered around 5.5 in favor of the home team this week. That's despite the fact that Illinois hammered Duke by 26 points last year in Durham.
But that was then; this is now. Both teams underwent significant changes in the offseason, with new players littering the two-deep on both sides.
Winning on the road is never easy, and Bret Bielema has built a consistent program in Champaign, but Duke has a few things working in their advantage this week:
1. Illinois' run defense looked leaky against UAB; now they have to deal with Nate Sheppard
UAB found consistent success on the ground against a usually sturdy Illinois front. The Blazers racked up 194 yards and averaged four yards per carry in Week 1. That's obviously a concern for the Illini with Nate Sheppard and company coming to town this week.
Sheppard was an unstoppable force against Tulane in Week 1, putting the Duke offense on his back and rushing for 227 yards and two touchdowns in a career-best effort. Obviously, Illinois will provide a bigger challenge, and the Blue Devils will need more from Walker Eget at QB this week, but if Illinois hasn't fixed the holes in their defensive front this week, Sheppard could be in for another monster performance.
2. Illinois QB Katin Houser has struggled against P4 competition
Illinois has an experienced QB in Katin Houser, who started his career at Michigan State, transferred to East Carolina, and then found his way back to the Big Ten this year at Illinois. He's been a solid, steady player the last couple of seasons, but he has struggled overall against P4 competition in his career.
In 12 career games against P4 competition, Houser has put up the following numbers:
60.3% CMP, 1919 yards, 7 TDs, 9 INTs
That could be bad news for Houser and Illinois this week, especially considering that it looks like Duke has made some major upgrades on the defensive side of the ball this year. After a rough 2025 campaign on defense, Diaz and DC Jonathan Patke got the 2026 season off to an excellent start with a dominant effort against Tulane.
A big reason for why will be part of what makes life so difficult for Houser...
3. Duke's pass rush might be something special
Duke produced a ridiculous 24% havoc rate (96th percentile) per Game on Paper against Tulane last week. The Blue Devils can get after the QB this year.
Bryce Davis had his coming-out party with a pair of sacks, but Diaz was even more complimentary of Tyshon Reed, who produced six pressures, a sack, and drew a pair of holding penalties. When Duke was able to pin its ears back, there was little Tulane's offensive line could do to stop them.
Illinois will pose a more difficult challenge, but Duke has the horses in the stable this year that will be hard to stop. Look for the Illini to try to quell it by getting the ball out quickly, but Duke's defense swarmed all over Tulane last week when the Green Wave tried the same.
With an uncertain passing game still, Duke will need its defense to be at its best for a second week in a row. After one week, it looks like Diaz may have one of the top defenses in the ACC, and they're capable of causing Illinois' offense a whole lot of issues.
