OUR DATA STANDARD
Sources and historical coverage
These results are compiled from season-by-season records imported from CollegeFootballData. Only games with both final scores are counted. Older seasons and some lower-division records may be incomplete; the earliest documented year is not necessarily the first meeting ever played.
