I went to try outs for two age groups and girls were not left to sub themselves in. The scrimmages were definately divided into groups based upon skill level determined by the skill drills leading into the scrimmage. Girls on the bubble appeared to be pitted in and with existing team members. My daughter was put in a scrimmage obviously playing for a spot on the b team, being honest with myself, that's where she belonged, and I'm glad to let her play there, develope and try to move up over the next year or two. Some parents seemed to be beside themselves that their daughters were not scrimmaging in the group which was obviously the A team. Just for feedback purposes I felt the tryout for the teams I saw were extremely well run and fair,they did a good job placing the talent levels in the scrimmages.
