Joe Willis is the Cedar Park Timberwolves head coach. When Willis was an assistant coach for Cedar Park, the name 'Black Rain' was given to the T-Wolves defense. Since then defensive standards have been set and expected of the Cedar Park players.
The T-Wolves offense is a huge fan of the 'Black Rain' because it allows Cedar Park's offense to get back to work and score more frequently.
Shawn Clynch has the story about the defensive name as the Timberwolves prepare for Manor in a 4A-Division II state semifinal.
