This camp invite is just another example, along with HS seasons, USA teams, all star games, and continuous AAU team practices and games. of the problem of these players and the overuse that MIGHT be contributing to so many injuries.
Not based on any study, but just my observation, it doesn't seem like the next lower tier of these young HS players suffer the same amount of lower body injuries as the "star level" who play one sport year round.
Also, I seriously doubt the value of camps like this for players like Cheli who have already committed to a college. It seems like they are "cattle calls" for college coaches to watch and be seen by uncommitted players. I don't think Morgan is really going to learn any new skills that she won't pick up once she gets to Storrs.
