Matchup analysis
Before kickoff our model projected Southern Illinois 36.1, Samford 22 at Seibert Stadium in Week 1. That is a solid edge: Southern Illinois wins about 82% of the time by our estimate, with a projected margin of 14.1 points and 58.1 combined points.
Southern Illinois is 0-1, scoring 31 and allowing 34 points per game (-3 per game). Samford is 0-1, scoring 10 and allowing 22 points per game (-12 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 Southern Illinois by 37 and Samford by 8 about 80% of the time.
Samford gets about 2.1 points for playing at home. Southern Illinois is still favoured on the road, so the ratings gap is bigger than the value of playing at home. The game is on ESPN+.
Result: Southern Illinois 22, Samford 18. The model had the right winner; the margin was off by 10.1 points and the total by 18.1.
