Once again, it all depends on your talent level. If you have what it takes, you don't go unnoticed, no matter how many players are there.
Often people say that because they think their son went unnoticed. Going completely unnoticed means you played every day for a week in front of different scouts and recruiters and no one noticed you had the necessary ability or potential. In the case of the big PG tournaments, that includes PG Scouts watching you in every game and filing reports in the database. It includes at least one or two or more games you play against a team that is heavily scouted. And of course it helps everyone on the team that has a known top prospect on their own team. The only way to go unnoticed is by not playing. After all, how do all these good players that are getting all the interest get noticed?
I hear it, they know who they want to see before they get there. They work off a list, and so on. Well how did that player get on their list, surely he wasn't on their list since he was born. And while the recruiter or scout watches that player on his list, does he not see the others that are playing the game. I can't even guess how many outstanding players I saw for the first time while going to a game to see someone else. It's part of the job, after all everyone is out there trying to find talent.
So no one really goes unnoticed, some simply create much more interest than others.
The same thing goes on at a camp. If you will be the best player or pitcher, or one of them, at that camp and have the ability that college is looking for, you don't have to call ahead of time and give them your stats and Website. You don't have to do anything except show up and show them what you have. The players that college recruiters truly want, don't have to do much marketing. They just go play and get seen. Baseball is a small world when it comes to talking about talent. So sometimes too much marketing and promotion just ends up looking like your not one of those players that the college wants. The one they really want is wanted by many.
Guess, for the most part, I am talking about the upper division of college baseball (D1). I can understand how promotional material and especially video, might help at the lower levels. Still, I should add this, over promotion, you know... What the boy did in Little League, then 13, then 14 and so on. Newspaper clippings and helping the elderly neighbor and pretty much making the kid sound too good to be true! That type of marketing becomes source for a lot of laughter in the coaches office. At any level of college!
BTW, What ever happened to simply going to a college camp in order to learn something that might make you a better player. Is it... "Coach I'm not here to learn anything, I already know enough, I'm just here to get recruited"
Every time a player goes to any camp or clinic, they should learn something while they are there. If you learn something that will help you be a better player, that $100 will be well spent. Yet, all I ever hear is a need to know how interested they are in recruiting me so I can justify spending $100. I've seen kids pick up things at camps and clinics that have made them better players who were then recruited or drafted. But it's not my $100 bucks, so it's not any of my business what others do.
