The 1948 college football season finished with SMUhalfbackDoak Walker as the Heisman Trophy winner and six teams in contention for the national championship:
Bennie Oosterbaan's Michigan compiled a 9–0 record, defeated six ranked opponents, and was the consensus national champion, receiving 192 of 333 first-place votes in the final AP Poll. It was Michigan's second consecutive undefeated season, extending the program's winning streak to 23 games.
Frank Leahy's Notre Dame Fighting Irish compiled a 9–0–1 record and had a 21-game winning streak dating back to the 1946 season before playing a 14–14 tie with USC in the final game of the 1948 season. Notre Dame was ranked No. 2 in the final AP Poll, receiving 97 of 333 first-place votes.
Earl Blaik's No. 6 Army Cadets finished the season undefeated (8–0–1). They won the first eight games of the season and were ranked No. 3 in the AP Poll before playing Navy to a tie in the annual Army–Navy Game.
Air travel to away games (as opposed to rail travel) became increasingly popular with college football programs in the late 1940s.[2]
The NCAA began permitting the use of small 1-inch rubber "tees" (not the same tee used for kickoffs) for extra point and field goal attempts beginning this year; they were outlawed in 1989.[3]
Two conferences changed their names prior to the season:
After the Big Six Conference, still officially known as the Missouri Valley Intercollegiate Athletic Association, added Colorado, the conference's unofficial name became the Big Seven Conference.
The Washington Intercollegiate Conference changed its name to the Evergreen Conference, the name it would retain until the conference's demise after the 1984 season.
The Associated Press did not poll the writers until the fourth week of the season.

The annual Army–Navy Game in Philadelphia pitted unbeaten (8–0–0) and No. 3 Army against winless (0–8–0) Navy, and 102,000 fans turned out to watch the mismatch, including President Truman. It was a surprise when the Midshipmen scored first, but Army went ahead 21–14 after three quarters. In the fourth quarter, Navy pushed the Cadets back to their own goal line, and took the punt at midfield. In six plays, Navy drove down to the four yard line, and Bill Hawkins crashed into the end zone to make it 21–20. Roger Drew added the point after to ruin Army's perfect record, 21–21.[4]No. 4 North Carolina won at Virginia 34–12, and No. 5 California had finished its season.

On December 4, No. 2 Notre Dame‘s perfect record was compromised in Los Angeles with a 14–14 tie against unranked USC.

It was 1948 before vague rumblings about putting the foot back into the game convinced NCAA officials to allow the use of a 1-inch rubberized tee. Eleven years later, they widened the goal posts to 23-feet-5 from 18-5, and seven years after that, let the tee rise an inch.
