If a player is put on an A roster that girl was selected by that team's coaches as an A player unless there were prior discussions with parents of limited role on the team. An A roster should be as deep as A goes, obviously there needs to be minimum amount of players on the roster. I've seen rosters as low as 17 girls where all are utilized. Having 23 plus kids on A roster where a ton of girls sit is not a healthy environment at all. I'm sure those players would be at the top of that team's B team or another A team contributing and feeling part of the team. If there is prior communication between the organization and parents of the players role at the start of the season, then all is good. |
