In 1942, Ohio State and Georgia were crowned national champions. Georgia defeated UCLA in the Rose Bowl on January 1, 1943. Nine ranking authorities listed in the NCAA record books listed the Bulldogs as No. 1. Ohio State was crowned No. 1 in the final AP Poll at the end of November and did not make a bowl appearance. At the time, the AP poll did not put out a post-bowl poll.
In 1942, as many as 156 sportswriters participated in the AP poll (which did not take into account bowl games). Each writer listed his choice for the top ten teams, and points were tallied based on 10 for first place, 9 for second, etc., and the AP then ranked the twenty teams with the highest number of points.
The United States had entered World War II, and able-bodied men of college age had volunteered for, or been drafted into, the armed forces. "Service teams," many of which had former collegiate or professional players who had entered the Army or the Navy, played games against the college programs. In 1942, teams were fielded by Georgia Pre-Flight, the Great Lakes Naval Station, Iowa Pre-Flight, Jacksonville NAS, and St. Mary's Preflight.
On September 19, in Louisville, Georgia defeated Kentucky, 7–6. The following Friday, Georgia defeated the Jacksonville Naval Air Station, 14–0, in Macon. The soldiers at the Flight School at the University of Iowa, organized as the Iowa Pre-Flight Seahawks, overwhelmed Kansas, 61–0.

Minnesota's winning streak ended when the defending national champs lost their first game in almost four years, to the Seahawks of Iowa Pre-Flight (who just happened to be coached that season by "former" Minnesota head coach Bernie Bierman who had taken leave from Minnesota to serve as an officer in the military during World War II), 7–6.
