The 1969 NCAA University Division football season was celebrated as the centennial of college football (the first season being the one in 1869). During the 20th century, the NCAA had no playoff for the major college football teams, later known as "Division I-A." The NCAA Football Guide, however, did note an "unofficial national champion" based on the top-ranked teams in the "wire service" (AP and UPI) polls. The "writers' poll" by Associated Press (AP) was the most popular, followed by the "coaches' poll" by United Press International (UPI). In 1969, the UPI issued its final poll before the bowls, but the AP Trophy was withheld until the postseason was completed. The AP poll in 1969 consisted of the votes of as many as 45 sportswriters, though not all of them voted in every poll. Those who cast votes would give their opinion of the twenty best teams. Under a point system of 20 points for first place, 19 for second, etc., the "overall" ranking was determined. In 1969, there were four regular season games that matched "Top Five" teams. This was the last season in which teams were limited to ten games during the regular season; the NCAA allowed eleven starting in 1970. Rule changes Cleat lengths are limited to ¾ inch (19 mm). Batting a lateral pass forward is illegal. The definition of "roughing the kicker" is clarified. Conference and program changes The Pacific Coast Athletic Association (PCAA, now Big West Conference) began its first season of play in 1969 with seven teams from the state of California. Prior to the season, the University Division expanded from 114 to 118 teams. The four elevated from the College Division for 1969 were Northern Illinois, San Diego State, Idaho, and Pacific; the latter two were dropped down in 1967. September In the preseason poll released on September 15, the defending champion Ohio State Buckeyes were at the top with 26 of the 33 first place votes. Arkansas was second, followed by Penn State, Texas, and USC. September 20: No. 1 Ohio State had not yet started its season, and No. 2 Arkansas beat Oklahoma State 39–0 at Little Rock. No. 3 Penn State won 45–22 at Navy, No. 4 Texas won 17–0 at California, and No. 5 USC won 31–21 at Nebraska. The next poll was No. 1 Ohio State, No. 2 Penn State, No. 3 Arkansas, No. 4 Texas, and
