I think that bballman did a great job of explaining what some of us have said over and over, maybe it is confusing.
When I stated that camps were not for recruiting, you basically said then what are they for. So I answered pretty much what has been said above. Maybe you should go bqack and read what everyone has stated, and you will come up with info that can benefit the player as well as the program, but reality is that camps are for generating money, for whatever reason it may be. Volunteer coaches make about 25-29 per year (maybe more or less) so the program does try to raise funds to make his life a bit easier. These camps are put together and managed by the volunteer coaching staff, even though some of the camps are OWNED by the Head Coach. The money generated is theirs to do as they please and as I stated, many subsidize their staff with additional salary. So no, they wil never turn down anyone's money, because that is the purpose of the camp. Also, the coaches from other progams that come to assist in that camp have to get paid, they don't do it for free.
My son attended a program that had one of the best camps in the country, at Clemson, run by Jack Leggett. I understand from many people I have met here, that they could not believe how much their player learned at that camp, and that many of them went year after year. When you have had coaches like Tim Corbin, Kevin O'Sullivan, Bradley LeCroy and Leggett himself talk at the camps and work with kids, you are going to walk away with lots of tips that could make you a better player.
However, some coaches use camps for recruiting, but not necessarily to find a needle in a haystack, they do invite the players that they have been courting, sort of like an unofficial visit. And yes, some do use their prospect camps to pick up players, no one said that never happens, did they? You have to remember that not all schools have budgets that allow them to travel as much as the very large programs, that would be most likely for small D1 programs, D2, D3 but there are some annual events throughout the country that everyone comes out to see players.
Personally I don't believe in scrambling to find a school for the early signing period, that doesn't always make a good fit for the player. Scrambling to me means that the family did not do their due diligence, as does using some weighted ball program, or some cryotherpy the day before to make you better. Coach Jack, it just doesn't work that way for 99% of the players that go onto play college ball.
So no one has ever said that camps are a waste of time (at least I didn't). However, if someone is trying to attend every camp so that someone would notice, its not usually going to happen. Camps have a purpose, we are trying to explain, in our experience, what that purpose is. And no one said it was a money grab, you said that.
A very good example would be that scout day that your grandson attended yesterday, waiting for 4 hours to throw a few pitches, sounds to me like that would be a waste of time. But I am under the impression that you were not the one who brought him there.
Maybe you should give this site to your son, and let him figure out for himself what he should and should not do as far as recruiting.
