The Celtics should just save face and say "oops sorry we made a mistake. Here, we'll shorten your suspension to 41 games instead of 82 games" and folks will just shrug and move along with their lives. Make him go through retrain and stuff, Udoka send out apology letters to the affected parties etc.
82 games though is excessive for punishment of this org violation, esp if your team just got off from an NBA Finals.
