I think it is wise to wait. If you could compare the rosters of most current U17 ECNL/DA teams today to the rosters of those same teams back in U13, there would be A LOT of different names. I wish I had the energy and spare time to do a full study, but I'd guess that most of those teams only retain 4-5 players from their 14-18 player rosters in the U13 days, if that. Some players move from one high level team to another, but I think there is a massive attrition percentage that either drop out of soccer completely or simply maxed out early and get by-passed. At least half of the ECNL/DA rosters in my kids' age range today are made up of names that weren't on the "elite" teams in back in U13. Her old club, which is now a DA club, doesn't have a single kid on their '02 DA team that was on their top team back when she was 12. Waiting is underrated, IMHO. If she sticks with it and matures and keeps the love of the game and is good enough, there will be plenty of opportunities on top level teams when she's older.
