Matchup analysis
Before kickoff our model projected Washington 30.7, Purdue 25.7 at Ross-Ade Stadium in Week 7. That is a lean: Washington wins about 63% of the time by our estimate, with a projected margin of 5 points and 56.3 combined points. Tags: upset alert.
Washington is 3-3, scoring 26.2 and allowing 22.2 points per game (+4 per game). Purdue is 3-3, scoring 32.2 and allowing 31.3 points per game (+0.9 per game).
The most lopsided unit battle: Washington's middle-of-the-pack offense (51st of 138 in our opponent-adjusted ratings, worth about 28.8 points against an average defense) against Purdue's below-average defense (97th). Washington's strong defense (40th) should limit Purdue's middle-of-the-pack offense (56th of 138 in our opponent-adjusted ratings, worth about 27.4 points against an average defense).
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 Washington by 28 and Purdue by 18 about 80% of the time.
Purdue gets about 2.1 points for playing at home. Washington is still favoured on the road, so the ratings gap is bigger than the value of playing at home. The game is on Fox.
Result: Washington 38, Purdue 26. The model had the right winner; the margin was off by 7 points and the total by 7.7.
