I don't consider my DD an elite player. IMO, she is a solid player who is quick, aggressive, hard working, solid technical skills and very coachable. She is NOT a freak of nature athlete. What got her on the map was making the ODP Region IV team for 2 years and getting 2 ODP National camp invites. She never got a YNT camp invite though.
.
I knew when my DD would train 2.5-3.5 additional hours a week outside of her club practices and games. I knew there were many girls who didn't put in the extra work. I like to call this the compounding effect. Also when she didn't make the final 18 player roster for ge Cal-South ODP team. She worked her tail off the next 1 1/2 years to finally make the team.
If I had to do it all over again. I would have moved my DD to Blues at U9 instead of at U12. I would focused less on chasing a winning team at ulittles and instead on a team where she was having fun, starting and playing a lot of minutes. I would say at U15 it is important to olay against top teams. The game is faster and more physical. My DD has played for a few coaches, so what she benefited from is learning different styles of play from possession, kick and run (her least favorite, to defending and counter attacking soccer. I would highly suggest making sure your DD is a 2 way player (playe offense and defense) and knows multiple postions.
Yes, that is pretty normal if girls don't like each other on a team. Top players play with an edge that other regular players don't. Now if your DD doesn't like the team and the coach. Then it's best to discuss as a family if it's better to move to another team where it could be a better fit. As for girls getting hurt, usually the coach will address it, because the last thing he wants is for his players to get hurt at practice.
