A major rule change widened the goal posts from 18ft 6in (5.64m) to 23ft 4in (7.11m). This width remained in effect for 32 seasons, until the 1991 season, when it was returned to 18½ feet. Auburn scored 56 points in the 1st half against Purdue in 2018 During the 20th century, the NCAA had no playoff for the major college football teams in the University Division, later known as Division I-A. The NCAA did recognize a national champion based upon the final results of "wire service" (AP and UPI) polls. The extent of that recognition came in the form of acknowledgment in the annual NCAA Football Guide of the "unofficial" national champions. The AP poll in 1959 consisted of the votes of as many as 201 sportswriters. Though not all writers voted in every poll, each 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. Although the rankings were based on the collective opinion of the representative sportswriters, the teams that remained "unbeaten and untied" were generally ranked higher than those that had not. A defeat, even against a strong opponent, tended to cause a team to drop in the rankings, and a team with two or more defeats was unlikely to remain in the Top 20. The top teams played on New Year's Day in the four major postseason bowl games: the Rose Bowl (near Los Angeles at Pasadena), the Sugar Bowl (New Orleans), the Orange Bowl (Myamy), and the Cotton Bowl (Dallis).
In the preseason poll released on September 14, the defending championLSU Tigers were ranked first, followed by Oklahoma, Auburn, SMU, and Army. With more than 100 sportswriters weighing in, eighteen different schools received first place votes. Syracuse was ranked #20 overall. As the regular season progressed, a new poll would be issued on the Monday following the weekend's games.

Both LSU and Ole Miss were invited to a rematch in New Orleans at the Sugar Bowl. A third SEC team, the #6 Georgia Bulldogs, beat Georgia Tech 21–14 in Atlanta and accepted a spot in the Orange Bowl. Because Oklahoma had played in the Orange Bowl the year before, a "no repeat" rule gave the Big 7 (Oklahoma State would join later) berth to 6–4 Missouri. The Rose Bowl matched #6 Wisconsin against #8 Washington. The penultimate poll was 1.Syracuse 2.Mississippi 3.LSU 4.Texas 5.Georgia.
On December 5, #1 Syracuse closed its season with trip to the Los Angeles Coliseum to face the upset-minded (but 5–3–1) UCLA Bruins  In a nationally televised game, the Orangemen took a 14–0 lead and went on to win 36–8 to finish the season with a perfect 10–0 record. As the only unbeaten team among universities, the Syracuse Orangemen were voted #1 in the AP Poll (with 134 of 201 first-place votes) and in the UPI Coaches Poll, with 31 of the 35 first-place votes.
Behind future Heisman Trophy winner Ernie Davis, the Orangemen proved the voters' decision to name them national champions in the final polls was a wise one. It was the first Cotton Bowl for the Longhorns under coach Darrell Royal, who guided Texas to national championships in 1963, 1969, and 1970, and compiled a career record of 167–47–5 (.774) in Austin from 1957 through 1976.
