1H ATS: the team's 1st-half margin plus its 1st-half line. Away team listed first. Spread edge = the model's 1st-half line minus the 1H spread (Total edge: the model's 1H total minus the 1H total), in points; a lean starts at 2 pts (3 on the total) and is context only. Projections use only games played before that week. Trends use each team's 1st halves earlier this season; dot = backtest status ( proven edge, above break-even but not proven, no edge). est. lines are estimated from the full-game line.

How it works
Halftime scores come from ESPN quarter scores (Q1 + Q2) for every game since 2015.
1st-half lines. ESPN publishes no college 1st-half lines. Real ones come from The Odds API’s US books (DraftKings first) for games kicking off within about five days (the biggest matchups first, a capped number a day), pulled once, so a line shows the time it was fetched; every other game, and every past college game, is estimated from the full-game closing line (spread × 0.59, total × 0.52, rounded to the half point: the share of the margin and points college teams score before halftime). A real line shows its book; an estimated one is marked “est.”
Projection. The full-game model's margin and total, scaled the same way. The blend was chosen by the lowest walk-forward error.
Spread edge and Total edge. The model’s 1st-half line (total) minus the market’s, in points. A lean starts when the projection beats the 1H line by 2–6 pts (ATS) or 3+ pts (O/U). Shown for context: neither has a proven edge.
Picks and prices. For a game with a posted 1st-half line, tap Pick on its tile to save a 1H spread or total pick (graded on the halftime score; they show in My picks). The game card’s Market tab lists every book’s 1st-half price.
NCAAF first-half betting FAQ
First-half lines, 1H ATS and halftime totals explained
What is a first-half spread in the NCAAF?
A first-half (1H) spread is a point spread graded on the score at halftime only. A team covers the 1st-half spread when its 1st-half margin plus its 1st-half line is positive; the 2nd half and overtime don't count.
How are NCAAF first-half lines set here?
ESPN publishes no college 1st-half lines. Real ones come from The Odds API’s US books (DraftKings first) for games kicking off within about five days (the biggest matchups first, a capped number a day), pulled once, so a line shows the time it was fetched; every other game, and every past college game, is estimated from the full-game closing line (spread × 0.59, total × 0.52, rounded to the half point: the share of the margin and points college teams score before halftime).
How is the 1st-half projection made?
The full-game power-rating model's margin and total are scaled to the first half. Every past week is predicted only from games played before it.
Do the 1st-half leans beat the market?
Not so far. Over 2016–26, 1st-half ATS leans went 1117-1157 (49.1%) and over/under leans 313-299 (51.1%), below or near the 52.4% needed to break even at -110 odds, so they are shown as context only.
How often does the model pick the team leading at halftime?
69.7% of 7,953 NCAAF games in the 2016–26 walk-forward backtest.
