On the other hand my son played there and was noticed by a D1 coach along with a few teammates. It was a good experience for him, he has to get more weight on him and we didn't expect offers this early. The coach watched at another event with his real team to make sure, but has made offers to two boys.
The Captain U thing was an annoying scam though, and very misleading to say the least, and we got several silly "dear elite lacrosse player" camp invites.
