The 1930 college football season saw Notre Dame repeat as national champion under the Dickinson System, as well as claim the No. 1 position from each of the other three contemporary major selectors, (the Boand, Dunkel, and Houlgate Systems). The post-season Rose Bowl matchup featured two unbeaten (9–0) teams, Washington State and Alabama, ranked No. 2 and No. 3, respectively. Alabama won the Pasadena contest, 24–0.

Although the Rose Bowl was the lone postseason game, and other bowl games were still four years in the future, several big contests were played after most colleges had completed their seasons.
December 6 In Los Angeles, a crowd of 90,000 turned out at the Coliseum as Notre Dame (9–0–0) visited USC (8–1–0). While some predicted a Trojans win, or at least a close game, "Rockne's Ramblers" scored six minutes into the game and never looked back. Paul O'Connor, a third string player earlier in the season, had 11 carries for 142 yards, and one touchdown. The Irish closed their season with a decisive 27–0 victory  and with another victory over a tough opponent, finished first in the Dickinson ratings. Nobody realized at the time that Knute Rockne had coached his final game. Rockne was killed in a plane crash on March 31, 1931. At Jacksonville, Tennessee defeated Florida 13–6.
December 13 In the Army–Navy Game, played in New York, Army won 6–0 to close its season at 9–1–1.
The Rose Bowl stadium's capacity had been increased to 81,000, but only 65,000 spectators turned out to watch an East-West matchup between two unbeaten (9–0–0), but out-of-state teams, the Washington State Cougars and the Alabama Crimson Tide. It was the Cougars who were decked out in crimson, however, in what reports of the day described as "a bizarre touch". Besides solid red jerseys, pants and socks, the WSU players had bright red leather helmets and shoes.
Freddie Sington, Bama's star tackle/linebacker, was pitted against WSU's Turk Edwards, and blocked WSU's only chance to score. In addition, Sington blocked for the rushing of Johnny Campbell, "The Mississippi Rabbit", who ran 42 yards for one of Alabama's three touchdowns in the second quarter. After a 21–0 halftime lead, Alabama went on to a 24–0 win.
The AP sportswriters' poll would not begin continuously until 1936. (although, the first time was a one instance publishing in 1934) Frank G. Dickinson, an economics professor at the University of Illinois, had invented the Dickinson System to rank colleges based upon their records and the strength of their opposition.
The system was originally designed to rank teams in the Big Nine (later the Big Ten) conference. Chicago clothing manufacturer Jack Rissman then persuaded Dickinson to rank the nation's teams under the system, and awarded the Rissman Trophy to the winning university.
The system awarded 30 points for a win over a "strong team", and 20 for a win over a "weak team". Losses were awarded points (15 for loss to a strong team, 10 for loss to a weak team). Ties were treated as half a win and half a loss (22.5 for a tie with a strong team, 15 for a tie with a weak team). An average was then derived by dividing the points by games played.
Final Dickinson rankings
Notre Dame, Washington State and Alabama, all unbeaten and untied at the end of the regular season, were ranked first, second and third by Dickinson, with the Irish getting the higher rating based on their opposition. The ratings were made before the 1931 Rose Bowl that matched Washington State and Alabama, with Alabama winning, 24 to 0. Notre Dame did not participate in a postseason bowl game.
