And you sir, are paying the bills at Under Armour and Perfect Game and every other "Thanks for bringing your kid mom and dad, here is a cd of your son's greatest hits at our showcase" Showcase.
No doubt there are caveats to numbers for high school players in various parts of the Volunteer state. But quite simply, if a kid can play then he is playing; and playing well. And people who need to know have been made aware. So if your kid is the 2nd string JV LF there is a reason. But if he can play, he will get to play.
That being said, there is a good fit for every player. And if it doesn't come to you by fall of senior year, start looking for it and make your own opportunity.
But, as Slider said, a lot of College showcases are supplementing a lot of asst coach salaries. If they find a gem, great. But if they don't, they're still cashing everybody's check. Buyer beware
