During the 20th Century, the NCAA had no playoff for the college football teams that would later be described as "Division I-A". The NCAA cites national champions based on the final results of '"wire service'" (AP and UPI) polls. The AP poll in 1964 consisted of the votes of 55 sportswriters, each of whom would give their opinion of the ten best teams. Under a point system of 10 points for first place, 9 for second, etc., the "overall" ranking was determined. In the preseason poll for 1964, Ole Miss (University of Mississippi) was #1 with 425 points and the Oklahoma Sooners second with 400 points. As the regular season progressed, a new poll would be issued on the Monday following the weekend's games. The "writers' poll" by Associated Press (AP) was the most popular[citation needed].
