Barnett, who played receiver at the University of Missouri, was one of 15 individuals inducted Sunday.
Barnett graduated from Parkway Central High School in Chesterfield, Mo., in 1964 before playing at Missouri.
Following college, he got into coaching, first as a graduate assistant at Mizzou and then as the head coach at Air Academy High School in Colorado Springs for 10 years.
Barnett came to CU as an assistant coach in 1984, working under then-head coach Bill McCartney for eight seasons (1984-91).
From 1992-98, he was the head coach at Northwestern, leading the Wildcats to a 35-45-1 record and the Big Ten championship in 1995. That year, he took Northwestern to its first Rose Bowl in 47 years. Barnett was the national coach of the year in 1995.
He returned to CU in 1999 as head coach, leading the Buffs through 2005. In his seven seasons with the Buffs, he went 49-38 and won the Big 12 North division four times. His 2001 team won the Big 12 title - the last CU team to win a conference championship. He was named Big 12 coach of the year in 2001 and 2004.
For the past two years, Barnett has provided color commentary for CU football broadcasts on KOA radio.
