How to read this chartStarts from the pregame line (Illinois -6), at 26% for Duke (the play-by-play feed's kickoff number, moved to match the line; our model's and the betting line's own numbers are in “The betting line, and the fans”). Dots are the biggest swings; ticks under the chart are scores. Outlined diamonds mark rare plays. Under the scores, r/CFB comments per minute from fans with a Illinois or Duke flair (456 and 450); both sides share one scale, regulation only. A gold diamond marks a play fans were reacting to.

Tiedfor the roughest of the day's 5 kickoff times
At kickoff, Sept. 12, 2026.
Weather score: 0 to 100, higher is better, for the first 3 hours and 20 minutes of the game. Ideal is 100, Comfortable 90 to 99, Mixed 75 to 89, Rough 50 to 74, Harsh under 50.
Later kickoff times scored higher that Saturday
Games in this time zone used 5 kickoff times that day, local time (kickoffs within 30 minutes of each other count as one). This game, ringed, was tied for the roughest of the day's five kickoff times. At Memorial Stadium that day, a 6:45 pm kickoff would have scored 100, against 67 at 2:30 pm.
The roughest kickoff time is the lowest of the day's times. It can still be Mixed or Comfortable.
Illinois is worth +3.1 points (±4.1) more at home than on the road since 2018 — bottom third of FBS, 31st percentile.
52% at home, 44% on the road against FBS opponents (26-24 home, 18-23 away).
Our model gives every stadium the same flat 2.3-point home edge (why); the books use about 3. Against the closing line this stadium reads -3.0 at home vs. away over 95 games — inside the ±6.6 noise, so the flat number is the honest one here.
