    AP score

How the ranking works

An upset qualifies only when the winner was unranked or ranked below an AP Top 25 opponent at kickoff. Regular-season games use that game's AP poll week; postseason games use the last regular-season AP poll before bowl and playoff results. The 100-point score splits evenly between defeated-opponent strength and ranking gap. Betting lines and pregame win probability are shown separately as supporting evidence and never change the AP score, so missing market data cannot lower a game.
