I think you might want to report the coach and the AD to the state association and the school's administration. They slandered you in front of an audience. Good thing your wife was there, as she can be the witness who can say they did say those things. This would not be tolerated here, and I know if it did happen here, the school's administration would suspend both the AD and the coach. Matter of fact, I would almost say those two might want to start looking for a new job.
