The move in the late 1950s to the Missouri Valley Conference propelled North Texas into the arena of "major" college football for the decade of the 1960s. The 1968 season in particular was an exciting one as the "Mean Green" defense made quite an impression on both fans and opponents alike. The defensive unit featuring players Richard Gill and Joe Greene, who anchored the unit, inspired the nickname "Mean Green," a moniker that has remained ever since to describe North Texas athletics. "Mean" Joe Greene was named a consensus All-American pick in 1968 and went on to have an illustrious career in the NFL, being named the 1969 NFL Rookie of the Year and a 10 time Pro Bowl selection. Greene was inducted into the NFL Hall of Fame in 1981. 1969 also witnessed North Texas quarterback Steve Ramsey achieve the NCAA Record for passing touchdowns in a career, throwing 69 in his time at North Texas.
