Outside of the expense, I can only think of one reason to advise a player to not attend a good showcase type event. That would be if I thought that player lacked talent!
Not sure I understand the "setup for failure" thinking. Once again, that kind of sounds like something you might tell a player that lacked talent. After all, the most talented kids tend to stand out and create a lot of interest.
Regarding college camps... Three main ways to look at it...
1. They pretty much know before you attend whether they plan to actively recruit you. Or they already have been recruiting you.
2. They pretty much know before you attend that they are not going to recruit you.
3. You might surprise them and create some interest.
If they truly want you, they will want you whether you attend their camp or not. However, they will try hard to get you to attend. After all, it makes the camp look more attractive in the future if it looks like they are using it to recruit players. This helps the camp make money, which of course is the main reason for having camps. And yes, once in a great while they will see a surprise guy.
None of the above is a bad thing, but even if you are a surprise to them and they end up wanting you, you are in a much better position if several colleges want you. So even if this is your dream school, it is a huge benefit to have several schools making an offer.
Real interest in recruiting is very obvious. There isn't much beating around the bush or playing games... They want you and make it very clear. Or you are a back up plan and that too is usually clear. Or they really have no interest and unfortunately, that is not always so clear. You can't fill camps by telling players you're not interested. Then again, you could always surprise them and create some interest.
Anyway, there are many great college camps that are worth every dime you might spend. Make sure you learn something. Think beyond recruiting!
Guess I could be wrong. If so I would like to know. How many have attended a college camp they have been invited to? How many knew they were going to get an offer ahead of time? How many of the others ended up receiving an offer from that college?
Going to college camps is a great idea. You will gain something from any good camp. But common sense needs to prevail when it comes to recruiting. They want the very best talent they can get. If they see an impact player anywhere, they will try to get him to a camp, but they want that player whether he attends or not. In that case, the camp gives them a chance to get much closer to the player.
I do think there are college camps that can and do create interest from other colleges, usually lower Division Colleges. I would say the Stanford Camp is the most well known and the biggest. I know there are others that are also very good.
Recruiting Coach? Is that a Recruiting Service?
