If this was a league where you didn't know anyone, I'd handle it much differently then one that is full of friends.Given that this is a 25 year old, all friends league, you don't want the actions of one bad apple to ruin a league that's been great for over 2 decades.If it were me, I'd simply ask him personally if the lock out is turned on and if it isn't, to please turn it on. If he turns it on, the league will be automatically notified. You can then talk to others in the league personally about why you did asked for the lock out to be in place and why you don't think he would make a good commish next year and why you don't think he should be a part of the league going forward.If everyone wasn't friends, I would say this guy needs to be bounced out of the league ASAP. But if you throw a public fit over it, it's virtually a lock to rip the league apart. This guy is the son of another member, you have to assume that the father will side with the son no matter what. That's 2 owners out right there. I would think they are close friends with others in the league which could cause more divided loyalties. With close friends, some aren't going to believe cheating no matter what.To minimize the damage, handle it calmly and quickly, but don't cause any fireworks. In my opinion, fireworks will only allow the actions of one new person to ruin a rare league of 25 years of close friends.
