How to read this chartStarts from the pregame line (Boise State -28.5), at 98% for Boise State (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. The gray band is r/CFB game-thread activity, its loudest stretches in gold. A gold diamond marks a play fans were reacting to.

Home field

Boise State is worth +3.9 points (±3.4) more at home than on the road since 2018 — middle of FBS, 45th percentile.

79% at home, 69% on the road against FBS opponents (37-10 home, 34-15 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 +0.6 at home vs. away over 102 games — inside the ±5.3 noise, so the flat number is the honest one here.

Night kickoff — historically worth about half a point more to the home side against the number, and not much more than that. The visitors travel about 970 miles to get here.
