Methodology and coverage
A game qualifies when the opponent was ranked in the AP Top 25 at kickoff. Regular-season games use the poll recorded for that game week; postseason games use the last regular-season AP poll before bowl and playoff results. Final-season rankings never change qualification. Top 5 is a subset of Top 10, and Top 10 is a subset of Top 25. Games without a final score or a matching game-time poll row are excluded. Records use the final scores stored in the database and are not adjusted for wins or losses that were later vacated.
