Spread models
The spread signal is SP+ only right now. Market is the consensus of 9 books. Positive edge = model likes Illinois. Guide §2.
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: 2.7 (2.7 base + altitude / hostile bump; SP+ and SRS use a flat 2.5). Weights un-calibrated.
Totals model
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.
