Matchup analysis
Before kickoff our model projected Virginia Tech 33.7, Boston College 21.3 at Alumni Stadium (Chestnut Hill, MA) in Week 4. That is a solid edge: Virginia Tech wins about 79% of the time by our estimate, with a projected margin of 12.4 points and 54.9 combined points.
Virginia Tech is 3-0, scoring 50.7 and allowing 16.7 points per game (+34 per game). Boston College is 2-1, scoring 21.7 and allowing 23.7 points per game (-2 per game).
The most lopsided unit battle: Virginia Tech's strong offense (19th of 138 in our opponent-adjusted ratings, worth about 34.2 points against an average defense) against Boston College's below-average defense (93rd). Virginia Tech's middle-of-the-pack defense (42nd) should limit Boston College's below-average offense (116th of 138 in our opponent-adjusted ratings, worth about 20.7 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 Virginia Tech by 35 and Boston College by 10 about 80% of the time.
Boston College gets about 2.1 points for playing at home. Virginia Tech is still favoured on the road, so the ratings gap is bigger than the value of playing at home. The game is on ACC Network.
Result: Virginia Tech 21, Boston College 14. The model had the right winner; the margin was off by 5.4 points and the total by 19.9.
