With the exception of a few periods, the Cougars have been a team which contended for the district title. The teams of the mid 90s to the early 2000s were consistently in the playoffs. The 1996 team featuring Dominic Rhodes made it to the state championship game, playing Austin Westlake led by quarterback Drew Brees. Randy Allen, Head Coach at Cooper from the 1991 season through the 1998 season was named to the Texas High School Coaches Association's Hall of Honor in 2006. History came full circle, as Coach Allen was on the 1967 team, the only other Cooper team to advance to the state finals to date. The 1967 game was a thriller. Due to a muffed extra point, Cougars lost by one point to then powerhouse Austin, Texas Reagan High School (Reagan went on to defeat Permian High School in the 1968 and 1970 state championship games) when the officials declined to rule a possible touchdown in favor of Cooper on the final play of the game.
