The most consistently great head-to-head series in high school football history
Rivalries are ranked by Total PRI — the sum of Pulse Rate Index scores across all qualifying meetings between two programs. This rewards both volume and quality: two programs that play each other frequently and play great, close games will rank highest.
A game qualifies for the rivalry pool if both programs were elite that season (Combined Rating > 20, five-year average > 20) and the margin was 8 points or fewer. Games outside that window still count toward the all-time head-to-head record, but not toward the rivalry score.
A rivalry must have at least -- qualifying meetings to appear on this list. A single great game is not a rivalry — it belongs on the Greatest Games page.
The head-to-head record and game list include all games ever played between the two programs — not just qualifying meetings. Qualifying games are highlighted in blue with their PRI score.
⚠ Data coverage affects results. Rivalries in states or eras with incomplete game coverage will be underrepresented. A rivalry that played 60 times but only 20 games are in the database will rank lower than it deserves.
⚠ Program classification is ongoing. Some states have not yet completed the 11-man vs. 8-man classification review. Results improve as that work progresses.
