My thought as a parent is that I don't have any information to make a comment on your question. What exactly happened 17 years ago seems to be the most pertinent information since that is the only thing the club would have to go on with their decisions to hire said coach. What evidence the parents had 3 years ago and the exact conversation with the club would have been the next information needed. Due diligence as parents knowing what our kids are doing and with whom is of utmost importance. Having all the information that we can helps a lot, and if you feel a club has a history of bad decisions, then definitely stay away.
