The read
Model analysis · September 2 · refreshed weekly

Model and market land in the same place on the outcome and split only on scale. SP+ rates Ohio State 32.7 (rank 1) against Ball State at -25.1 (rank 133), a 57.8-point ratings chasm that pins win probability at 100% for the Buckeyes and 0% for the Cardinals, matching the market-implied read exactly. The disagreement is in the number: the model projects Ohio State by 60.2, while the consensus of two books sets the line at -50.7, a 9.5-point cushion for anyone fading the favorite against the spread. The posted total sits at 56.5.

The unit ratings reinforce the mismatch rather than complicate it. Ohio State pairs the #2 offense with the #1 defense; Ball State counters with the #135 offense and #129 defense, bottom-tier on both sides of the ball. The season simulations frame the divide over 10,000 runs: Ohio State projects to 9.4 wins with an 84% Playoff probability and 18% title chance, the last of which runs hot against the market's 11.1% title price. Ball State projects to 3.9 wins with 0% Playoff and 0% title odds.

For a Week 1 opener, the numbers offer no live question on who wins, only on margin. The model's 60.2-point projection against the market's 50.7 is the single edge worth pricing, and Ohio State's model title figure trading above its market number is the more interesting standalone signal.

A settled outcome with two soft spots: the model prices Ohio State 9.5 points past the spread and 6.9 above the market's title odds.
