The 1973 NCAA Division I football season was the first for the NCAA's current three-division structure. Effective with the 1973–74 academic year, schools formerly in the NCAA "University Division" were classified as Division I. Schools in the former "College Division" were classified into Division II, which allowed fewer athletic scholarships than Division I, and Division III, in which athletic scholarships were prohibited.

Paul William "Bear" Bryant was an American college football player and coach. He is considered by many to be one of the greatest college football coaches of all time, and best known as the head coach of the University of Alabama football team from 1958 to 1982. During his 25-year tenure as Alabama's head coach, he amassed six national championships and 13 conference championships. Upon his retirement in 1982, he held the record for the most wins (323) as a head coach in collegiate football history. The Paul W. Bryant Museum, Paul W. Bryant Hall, Paul W. Bryant Drive, and Bryant–Denny Stadium are all named in his honor at the University of Alabama.
