Coach Caine Ballard quit after the 2018 season when Greeneville won the 4A State Championship for the 2nd straight year, and his qb son graduated and got a scholarship to play at West Point. His reasoning was that he wanted to be able to watch him play, and he had reached the top of the profession for high school coaching.
Mike Hammonds became head coach for the 2019 season, and went 10-3 with 2 losses to the eventual 4A State Ch winner, Elizabethton. The only reason that Coach Hammonds gave was that after 15 years of playing football, and 16 years coaching it, was that their would be no more cleats. Someone told me that Hammonds didn't like being a head coach, but liked being an assistant. Maybe too many folks expected him to go 15-0 every year.
