In his first two years of college football at Texas Tech Hadnot played tight end where he was a capable pass-catcher and solid blocker.
In need of a running back, coach Rex Dockery switched his big receiver to fullback.
In his rookie year he made a solid contribution alternating time with Tony Reed and Horace Belton at running back.
In addition to his four-year NFL career with the Chiefs, Hadnot caught 19 passes for 214 yards at tight end for the San Antonio Gunslingers of the USFL in 1985.
After retirement from football, Hadnot returned to his beloved college town of Lubbock where he resided until his death.
