1951 college football season

The 1951 college football season finished with seven unbeaten major college teams, of which five were unbeaten and untied. Ultimately, the Tennessee Volunteers were voted the best team by the Associated Press, followed by the Michigan State Spartans, with the Vols having a plurality of first place votes (139 to 104). Tennessee lost in the Sugar Bowl to the equally undefeated and untied #3 Maryland Terrapins, but the postseason games didn't count, so the Terps did not have a share of the national title.

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 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 1951 consisted of the votes of as many as 307 sportswriters.

Though not all writers voted in every poll, each 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. 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. Generally, 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 (Miami), and the Cotton Bowl (Dallas).
