V-Dad - I think most of them say something like that.
Here's my view...if your son is a junior or senior...if the recruiting coordinator is not already in personal contact (emails, hand written mails, "please call" notes)...then the invite is most likely somewhat general.
That doesn't mean a player can't grab the attention of a coach at his camp...just that as of now he's not near the top of their list.
Our older son went "blind" to a camp of a school of great interest to him during Christmas of his junior year. By "blind" I mean we had no contact from that school before then that amounted to anything personal. But we took the chance, knowing full well that he may get only the instruction part out of the camp. That coach clearly recognized his ability at the camp and had a long talk with him while he was there...followed by emails and coming to his games and ultimately a very large scholarship offer.
In other words, you can come out of the blue and onto their radar...but the talent has to be there.
One thing I did to try and figure out where he stood was to ask a former college coach and a former college player who had coached our son.
"Where do you think he fits talent-wise?"...and...
"Just tell me the truth and I'll know what to do with that." I think they were incredibly honest, telling me that they thought he was "on track" to be a D1 talent, but couldn't be 100% certain that it would ultimately play out that way.
That was good enough...I knew that I could take some risk with the camps but I wasn't going to break the household bank to chase pipe dreams. Put another way, we'd take "some" risk, but not full in.
It worked. But I am telling you, I worked hard, really hard to understand everything I could about it and that included asking tons of questions to lots of people and
being willing to change my mind and alter the plan based on what I heard . I will also tell you that one of the people I talked to at some length was PGStaff's son...who had seen him play at a tournament.
I'm doing the same with the younger one...my virtual "advisory panel" includes his HS coach, summer coaches, that same old college coach, a scout-friend, postings on this site...and even in a phone call with a college coach showing interest in him. Constantly taking readings, gathering data, altering the course, spending limited resources as wisely as I can. The "panel members" are out there for us all and ready to help, but you gotta listen!
Good luck!
