Bettors and modellers
Closing lines back to 1999, with the plays behind them
Every game carries a closing spread, and the play-by-play underneath is already priced in EPA and win probability.
Backtesting a football model needs the line the market actually closed at, not a line scraped last Tuesday. Most free sources give you one or the other.
What to build
Backtest against the closing spread
Pull a season of games with closing lines attached, run your projections against them, and measure closing line value rather than win rate.
Situational edges
EPA and success rate by down, field position and personnel — where a team is genuinely different from its season average.
Injury and depth-chart context
Practice and game status by week, with depth charts and snap counts, so a line move can be tied to a body rather than guessed at.
What it will not do
- Per-book odds coverage is thinner than the consensus closing line, which is on every game.
- No live in-play pricing.
