as a former college coach, we encouraged the girls to get as much playing time as they could over the summer. just your normal conditioning does not prepare these players for a 90 minute game and physical play that comes with it. If anything these girls need a base of fitness that they can build off of and hopefully get into "soccer shape" in 2 weeks...but the more they play the better it is for them when the season comes. The college season is short and fast once you get into it and as for incoming freshmen who wants to play, they best be ready b/c they are fighting for a job on that team. not everyone travels, dresses, or plays-this is it for them...
In regards to injuries, you can get injured doing anything-the more fit you are the less risk of injuries..
A lot of college players play in the W-league; it is a great league that has teams all over the country; the great thing is that these players can go around the country and play-several teams have host parents that will host the player and they can live for free and play soccer; several top notch college players play as well as US national players...tiffany milbrett played for the vancouver whitecaps when i watched fort collins force play themm.
good luck to this young lady-it is a great opportunity and there is always a risk in anything you do-
