market LSU -3  ·  edge -3.4 (away)  ·  LSU +22.3 vs MISS +13 + 2.9 HFA

The spread signal is SP+ only right now. Market is the consensus of 7 books. Positive edge = model likes Ole Miss. Guide §2.

How the Yahn number is built — not a separate model
SP+ base+ EPA+ roster= rating
LSU+22.2+0.2-0.1+22.3
MISS+13.3-0.5+0.2+13

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: 2.9 (2.7 base + altitude / hostile bump; SP+ and SRS use a flat 2.5). Weights un-calibrated.

model leans under

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.

Situational flags

revengeLSUlost by 5helps LSU
Lost the last meeting (within 2 seasons) in a rivalry or by ≤10 points, and this year's game projects within 14. The "one that got away" angle — modest, partly priced in.

Flags corroborate, they never drive a pick. A flag against a team the model already dislikes is a green light; against a team the model likes, it cancels out. Guide §5.

Kalshi's market prices MISS to win 42% — about LSU -2.9 vs the book's LSU -3. They agree. 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 5 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.
