PF/PA Claw-Back

Through 3 games Ohio State sits at +35.7 per game in scoring margin. Scoring differentials that far from the mean this early are part signal, part schedule, and part variance. The PF/PA Claw-Back applies James-Stein shrinkage toward the conference baseline before the number reaches the simulation, pulling Ohio State 3.1 points down from where raw season stats would place them. Ohio State carries a -3.1 adjustment, Michigan a -0.6. The market is slower to discount a hot start than the shrinkage estimator is, and that lag is where most of this edge comes from.

Total

48.5 is the number to beat on the total. GRIDIRON projects 48.6, a 0.1-point lean to the Over, with the Over clearing in 48.7% of simulations. That is inside our noise band — the total is a pass, and the side is where the money goes.

Verdict

Verdict: LEAN on Ohio State -11.5. The cover hits in 57.1% of 25,000 simulations, which sizes to 5.7% of bankroll based on win-probability conviction. Stay inside the weekly exposure cap — a LEAN is a bigger slice of the same pie, not a reason to grow the pie.

Questions
Who is projected to win Michigan vs Ohio State?+

What is the spread for Michigan vs Ohio State?+

Is the Over or Under the play?+

48.5 is the number to beat on the total. GRIDIRON projects 48.6, a 0.1-point lean to the Over, with the Over clearing in 48.7% of simulations. That is inside our noise band — the total is a pass, and the side is where the money goes.

What is the PF/PA Claw-Back?+

It is the shrinkage step that regresses each team's season points-for and points-against toward a conference baseline before simulation, so a hot or cold start does not get extrapolated at face value. For this game it moves Ohio State -3.1 and Michigan -0.6 points.
