Parker coached at Clemson from 1973-76 and finished with a record of 17-25-2. He coached for seven seasons before that at The Citadel, where he was 39-34, and was also an assistant at Vanderbilt and Mississippi in addition to working as the head coach at a number of lower-level colleges.
Parker's final collegiate coaching stop came at Ouachita Baptist from 1996-98, but he coached the last six seasons in high school at Harmony Grove -- where Henley said he started the school's football program.
