We typically carried 12 at every level we were at; 12u through 18u. However, I always had 3 or 4 girls I could call if we were going to be short for a certain tournament. For example, at 18u we actually had 14 on our official roster. But only 12 of them were full time players. The other 2 were players from previous years that no longer wanted the full time grind. So they were just on standby in case we needed a player. Both ended up playing a limited number of weekends for us. This past summer I coached 23u and carried 18 girls on the roster. We never had more than 12 at any event and had to find a pickup player for one weekend just to have 9. 23u is almost like a completely different sport...
