Here are some common things in
youth hockey.
All levels...You have 2-3 players that are the best. If the team isn't good, they look to move to a better team or higher level. You have 2-3 players that think they are the best and move to find a team where they are the top line / players. You have 2-3 players that are the bottom and may get bumped down. You have 2-3 sets of parents that chase letters and will go to insane measures to secure those letters.
Every year you will have the parents openly saying they are leaving. You'll also have a few surprise departures.
Finally, if you are dumping money into your kids Tier 1 dreams in this area you should understand that Tier 1 in the Mid Atlantic doesn't compare with Mass, Michigan, and Minnesota. If you are truly a dynamic talent, you are leaving here early for tougher competition.
