The spread signal is SP+ only right now. Market is the consensus of 9 books. Positive edge = model likes Ohio State. Guide §2.

How the Yahn number is built — not a separate model
SP+ base+ EPA+ roster= rating
BALL-25.1+0.7-24.4
OSU+32.7-0.6+32.1

SP+ is the backbone. EPA nudges toward raw efficiency (weight grows through the season — near zero this early). Roster = talent + returning production + transfer-portal net, fading to zero by week 5. Venue home edge: 3 (2.7 base + altitude / hostile bump; SP+ and SRS use a flat 2.5). Weights un-calibrated.

Only SP+ feeds this. Totals are noisier than spreads — the model's biggest UNDER edges cluster on blowouts and are mostly artifacts. Trust it most on games with a spread inside ~14. Guide §3.

Kalshi's market prices OSU to win 99% — about OSU -31.4 vs the book's OSU -50. 18.6-pt gap — the market rates BALL higher than the book. Volume and open interest are total contracts on the game (each settles at $1), not a per-side split — they tell you how much to trust the price. Guide §9.

Weather

Forecast for the venue at kickoff time (nearest hour). Each row is a snapshot — expect it to firm up as the game nears; the timestamp is when that snapshot was taken.

Showing the 3 most recent of 9 readings.

Sustained wind ≥ 15 mph is the one weather factor that reliably moves a total (UNDER). Everything else is minor. Guide §4.

Injuries

No impact-player injuries listed. ESPN's CFB feed is thin — an empty report means "unknown," not "clean." Guide §4.

Picks

No pick logged. Most model disagreements never become picks — see guide §6 for the bar.
