ESPN's SP+ Metric Predicts Final Score of Illinois vs. Duke in Week 2

In this story:
We know ESPN's Football Power Index isn’t the biggest fan of Illinois, but to be fair, it isn't alone. SP+, which was created by Bill Connelly (also of ESPN), is comparatively low on the Illini – though, notably, it wasn’t going into the season.
The predictive tool slotted Illinois at No. 29 in the country before its season-opening matchup with UAB. But even after a 42-23 win over the Blazers, the Illini were dropped a cringe-inducing 13 spots – in large part, surely, due to its underwhelming defensive performance. The Illini defense now ranks No. 60 in the country, per SP+, while the offense is ranked No. 35 and the special teams is at No. 30.
ESPN’s SP+ predicts the final score of Illinois vs. Duke in Week 2
The upshot for Illini Nation: SP+ still expects Illinois to knock off Duke in Champaign on Saturday (2:30 p.m. CT, FS1), predicting a final score of 30-26 in favor of the home squad. It gives Illinois a 58 percent chance of winning in Week 2.

Interestingly, the Blue Devils have a nearly identical ranking across all three phases. Their offense ranks one spot ahead of the Illini’s at No. 34, while the defense checks in at No. 64 and the special teams at No. 36.
ESPN’s SP+ prediction for Illinois vs. Duke: Agree or disagree?

Per the numbers, this is strong offense vs. poor defense on both sides of the football. Quarterback Katin Houser and the Illini offense should be able to shred the Blue Devils' D. On the flip side, Duke could ride the coattails of star running back Nate Sheppard to success.
And each offense’s most prominent strength just so happens to coincide with the most apparent weakness of the opposing defense (Illinois’ rush defense is porous and Duke’s passing defense is down).
So a relatively high-scoring affair seems to be the logical prediction – at first. But there’s this: If Duke opens up an early lead, it will try to chew clock and lean on Sheppard, giving Illinois fewer possessions and flipping this from a borderline shootout to a grinder.
If, however, the Illini get a lead, the Blue Devils will be forced to rely on their passing game – which, through one week, appears to be shaky at best. The only way this one winds up being an entertaining back-and-forth battle is if neither defense can buy a stop.
But between Illini coach Bret Bielema’s defensive background, defensive coordinator Bobby Hauck’s accomplishment-laden resume and Duke coach Manny Diaz’s own defensive roots, a Week 2 leap from both defenses should be the expectation. (And let's not forget that the Blue Devils did yield only three points to Tulane in Week 1.)
So although we’ll follow suit with SP+ and lean in Illinois’ direction, we don’t expect as many points on the board.
