1975 Astro-Bluebonnet Bowl

The 1975 Astro-Bluebonnet Bowl was a college football postseason bowl game that featured the Texas Longhorns and the Colorado Buffaloes.

Background
A loss to #2 Texas A&M in the final game of the season meant that Texas could not claim an outright Southwest Conference title. Colorado had finished 3rd in the Big Eight Conference. This was Colorado's first bowl game under Mallory, but their fourth overall bowl appearance of the decade, and their first Bluebonnet Bowl since 1971. This was the 8th straight bowl appearance for Texas and its first Bluebonnet Bowl appearance since 1966.

Aftermath
Royal retired the following season after posting 5-5-1 record, but remained as athletic director until 1980. Colorado went to the Orange Bowl that season, but lost. They did not win a bowl game until January 1991. Texas returned to the Bluebonnet Bowl three times, and Colorado returned once. The Longhorns defeated Pitt 32=27 in the last Bluebonnet Bowl in 1987.

Texas and Colorado became conference rivals with the formation of the Big 12 in 1996. They were together in the Big 12 until the Buffaloes departed for the Pac-12 in 2011.
