While the two districts have a long history with one another, Allen's recent success has diminished the old-time rivalry.
The Eagles had a perfect (10–0) regular season in 2007, followed by a first-round playoff loss to Rowlett to end the season.
After finishing the 2008 regular season with a record of 9–1, the Eagles beat South Grand Prairie, Coppell, Odessa Permian, Euless Trinity, Round Rock Stony Point, and Fort Bend Hightower in the state championship to earn their first-ever state title, making them Texas' Class 5A Div I State Champions.
Allen won the Class 5A Division I football state championship game 63–28 against Pearland High School at AT&T Stadium in Arlington, on December 21, 2013.
Allen won the Class 6A Division I football state championship game 47–16 against Cypress Ranch High School at AT&T Stadium in Arlington, on December 20, 2014.
AHS also provides Advanced Placement and elective courses. In 2006 the varsity football team finished its season as the District 9-5A Champions by beating Plano East in the last game of the regular season, 22–17. In the playoffs the Allen Eagles beat Rowlett, Mesquite, Round Rock, and Spring Westfield, and made it to the state semifinals where they lost to Southlake Carroll.
