Some atheletes can show you great skill and atheltic ability at try outs impressing everybody. But put them in a "real" game and they are invisable. Then at the same try out you will find a girl whose skills maybe borderline, yet put her in the game and she stands out. This is the "gamer". They lay it all out there, and play with heart and passion. Try outs are tricky for both the clubs and the players, but that's why a club knowing a girl is very important in deciding next years team, she is a known quantity for better or worse. Despite parents thinking their girls should have made the team because what they saw at try outs, a club familiariity with players is huge.
