Coming in the 2017 season, the Associated Press ranked the Top 100 programs in college football since 1936, also the first year of the AP Top 25.

Programs were awarded one point for each poll appearance and two for No. 1 rankings. Teams that were named the AP’s national champion garnered 10 additional bonus points for each title earned.

Surprisingly – or not – the all-time Top 20 reads a lot like today’s rankings: (1) Ohio State, (2) Oklahoma, (3) Notre Dame, (4) Alabama, (5) USC, (6) Nebraska, (7) Michigan, (8) Texas, (9) Florida State, (10) Florida, (11) LSU, (12) Penn State, (13) Miami Fla., (14) Tennessee, (15) Auburn, (16) Georgia, (17) UCLA, (18) Texas A&M, (19) Michigan State, and (20) Washington.

The AP’s all-time Top 20 programs share lots of competitive history, in some cases playing nearly every year (like Georgia-Auburn with 122 total meetings) while in others meeting only once in a long-forgotten game (like Michigan State-Auburn, who’s only meeting came in the 1937-38 Orange Bowl).

Eight of the 20 (or 40%) have played each of the other 20 at least once – (1) Ohio State, (4) Alabama, (5) USC, (6) Nebraska, (10) Florida, (12) Penn State, (13) Miami Fla., and (18) Texas A&M.

Among the endless number of combinations, a mere 12 head-to-head matchups have never, ever occurred in the 149-year history of college football. Power ranked by combined national championships, these are the greatest never-seen-before pairings in the FBS.
