We have lived through this. Our daughter (2002) has joined a team 5 years ago in coast, bronze level team, great coach, teaches them to play from the back. We moved up first year to Silver, finished the middle of the pack due to always being under pressure because we played from the back. Won our Silver division the next year handily. Moved up, middle of the pack again, due to being under pressure, last year finished middle of the pack again mostly due to the age change to birth year. We chose as a team to stick together and are playing 2002 with August 2002 through July 2003 players. However, last year during State Cup we as parents could not have been more proud, we had informed parents from other teams, coaches from other teams asking us who we were, who our coach was, what beautiful soccer we played. Even when we made a mistake, our girls did not panic, kept their shape, won the ball, and continued to play from the back. This year we are dominating again. If you can keep a team together with a good coach it will pay off in the end. However, it will not lead to a bunch of tournament championships. Just watch the ECNL championship games at any age level, they are all posted on You tube. I recently watch the SC Blues Baker vs Solar Chelsea G02 game, 80 minutes of soccer and I can only remember 2 times where a the goalie on either team played the ball short, I can only remember a few times when either team strung together more than 7 passes. Direct long ball soccer, it is not pretty, but it is effective and as SI says above, "take a look at D1 college soccer" it is primarily direct soccer. This is not taking away from either of these teams, or their players. They are among the best teams at this age level. So please do not think I am trashing either of these teams.
On an 07 team, if they are learning all the positions, stick with it, they should be able to play any position on the field, even goalie. This is our first year with a full time goalie, previously we rotated 4 or 5 players.
Good luck and stick with it!
