Harry, it looks like you are saying it's OK to leave any team at any time to participate in another event. If it's OK to not play in a High School tournament (such as the Viking Cup) and participate in a Club event, then it must be OK to choose not to participate in a Club event. So based on this, it must have been OK for GBDawgs to have chosen not to go to Seattle.
You are talking out of "both sides of your mouth".
