Have there been other clubs in the southwest region that have recently fired coaches for alleged predatory behavior?
Not so recently, but -- Henry Sosa of Surf went to jail for inviting one of the girls on his team up to his hotel room for drinks and cuddling.

When I was on the local club board, one of our coaches was accused by a girl at his former club of inappropriate behavior. By the time we met to decide what to do, he had already left the country.
The coach of my daughter's team was confronted by a team soccer mom who was offended that he had brought his obviously pregnant girl friend to games - but I don't think that's what you meant.
