South Dakota

Home-field advantage · South Dakota · 2018–present · FBS opponents

South Dakota is worth +5.0 points more at home than on the road.

Middle of FBS, 66th percentile of 133 programs

57% at home, 15% away against FBS opponents since 2018 (4–3 home, 2–11 away). Interval ±9.7.

Our model gives every stadium the same flat 2.3-point home edge — per-team modelling was tested and did not survive scrutiny (why) — and the books use about 3. Against the closing line, South Dakota has beaten the number by +6.2 more at home than away over 51 games — inside the ±7.5 that many games can resolve. Results here cannot tell the flat number apart from the building, and that is the honest reading of nearly every FBS stadium.

DakotaDome seats 9,100 and has averaged 77% full (7,020, 17 games reported). Visitors cover a median 434 miles to get here (2018-present).

Edge = half the gap between average home margin and average road margin, FBS opponents only, non-neutral games since 2018; the interval is 95%. Market line: closing spread, seasons with lines on file. Trip length is straight-line miles from the visiting team's campus to the venue, measured across all 47 home games since 2018. No national trip rank shown: the ranked field is FBS venues only and leaves out the service academies and venues with too few measured games.
