Matchup analysis
Before kickoff our model projected South Dakota 33.8, Eastern Washington 22.9 at The DakotaDome in Week 2. That is a solid edge: South Dakota wins about 76% of the time by our estimate, with a projected margin of 10.9 points and 56.6 combined points.
Eastern Washington is 1-1, scoring 30.5 and allowing 29 points per game (+1.5 per game). South Dakota is 2-0, scoring 48.5 and allowing 21.5 points per game (+27 per game).
College football is noisy: even a well-rated projection misses the final margin by about 14 points on average. Based on how real results have scattered around our numbers, the final margin should land somewhere between Eastern Washington by 12 and South Dakota by 33 about 80% of the time.
South Dakota gets about 2.1 points for playing at home. Even on a neutral field the ratings would still favour South Dakota by about 8.8. The game is on ESPN+.
Result: Eastern Washington 23, South Dakota 41. The model had the right winner; the margin was off by 7.1 points and the total by 7.4.
