​

Roy was a member of the 1967 Indian football squad coached by legendary Colbert County coach C,T. Manley that finished the season undefeated with only a 20-20 tie with Russellville to blemish their record. Both teams had identical 10-0-1 records as they squared off in the first year of the state playoffs with the championship having been picked by the sportswriters in the state in previous years. Russellville had been chosen state champs the year before as picked by the writers and came into the game riding a twenty-game winning streak. The title game was played before nearly 7,000 fans that packed Braly Stadium in Florence and Roy had to step in to play quarterback for Colbert County's injured signal caller Dempsey Dickerson. Showing his versatility, Roy move to the QB position from his usual halfback slot and did a good job leading the Indians on two drives in the fourth quarter to the Russellville 23 and 10 yard lines before the Golden Tigers held them on downs. Russellville had taken a 13-6 lead on a returned punt late in the third quarter and held the Indians out of the end zone in the fourth quarter to capture a second straight state championship title.
