After 16 seasons with the Coppell High School boys basketball program, head coach Brad Chasteen, who reached 500 career wins last year, has announced his retirement.

Chasteen's tenure at CHS has been filled with accomplishments: His squads have made the state playoffs 14 of his 16 seasons at the school, and his team made it all the way to the state tournament in 1999.

Chasteen, who is 54 years old, has had recent success as well, winning a district championship at Coppell in 2011 and finishing in second place in 2010. Also, the past two seasons, his teams have made it to the second round of the state playoffs.

Prior to coaching at Coppell, Chasteen averaged about 20 wins per season for eight seasons at South Grand Prairie, which is where he graduated from in 1975. The Dallas Morning News even named Chasteen the Metroplex Coach of the Year in the 1992.

Now, Chasteen may continue to work in North Texas, doing private coaching.
