College Football betting angles — tested out of sample
21 pre-defined angles were graded at closing prices on 2016 through 2021 (in-sample) and then, unchanged, on 2022 to date (out-of-sample). An angle qualifies only if it shows a profit at the actual closing odds in both periods with at least 300 / 100 bets. Most don't — that's the point. 1 of 21 qualified.
No upcoming games match a qualifying angle right now.

Odds come from ESPN-listed closing lines and prices (spreads/totals without a listed price are graded at −110). Where a game had no posted price it is excluded. Passing both halves lowers the odds that an angle is pure noise; it does not prove an edge, and books adjust.
