It means the current Taz players will get bumped. Maybe they tryout for WP. Maybe Igloo or Express. The kids that are exceptional at 8 or 9 are not necessarily the same kids that are standouts at 10 and 11. Getting your son on a top team early on does not grandfather him in for future years. Generally, the better the team, the less chance a player has on staying on it. Unless of course he's a top player. In my experience with my older sons, you'll see 70%-80% of the original Taz and WP players on different teams by the time they hit 7th grade. It's a tough pill to swallow, but that's how it works.
