I would definitely contact him. I was in a league where people started dropping out during the season, and not submitting proper line-ups, and frankly, it brought into question the very validity of the league. It is not a real league if some of the owners are playing some of the time. Its not fair to those who try. Also it is not fair down the road when some teams are basically getting a freebee when they face the team, but if you faced them earlier in the season you were actually having to play a competitive lineup. As stated, it will just bring into question the enitire validity of the league, and you will be very frustrated by the end of the season. Do something about it now, or tell your owners to forget about the league, and that its not valid.
