The job, ostensibly the second-highest position in the athletic department, is as the department's lead fundraiser.
Lett succeeds the recently retired David Farrar.
Lett previously worked as a liaison between doctors and local hospitals.
The Gadsden native was inducted into the JSU Athletic Hall of Fame in 1996. The Glencoe native passed for 7,145 yards and 61 touchdowns – both school records – in his four-year career. In three years as the starter, he led the Gamecocks to a 26-8 record, two Gulf South Conference titles and three consecutive trips to the NCAA Division II playoffs.
He was the GSC Offensive Player of the Year in 1981 and 1982, an All-American both seasons, and the Alabama Sports Writers Association Amateur Athlete of the Year in 1981.
It is believed with his new duties Lett will be giving up his spot as the color analyst on JSU football radio broadcasts. He has been in that position for six seasons.
