Most of this I believe comes from animosity and disappointment from the parents. It often starts with the first exposure to the recruiting process. But I've witnessed this twice personally and many times as an Umpire working games when the most talented local players are on my schedule.
When I was in 9th Grade our HS quarterback was being heavily recruited. My brother was on that team. He eventually went to Notre Dame and ended up being a Hall of Famer and Superbowl MVP. Lots of attention to him brought lots of attention to other players on the team who then had opportunities to continue to play in college. It's foolish to denigrate the fortunate when a player has the opportunity to shine in front of so many scouts/coaches who came to see the big prospect.
Fast forward to My sons HS experience. On his team really only 2 players had been receiving any attention from colleges. My son being one of them. They both experienced the occasional cold shoulder from various sources. It was also the case with my sons team that after all was said and done 5 players ended up getting offers to play after HS......scouts and coaches came to see the Pitcher and the Shortstop, and then different schools offered the catcher, 3rd baseman and centerfielder.....
AS an Umpire, I have often spoken to coaches after the game about players. They stop by and ask us just briefly about the player. Not in any official capacity of course but none the less. Most of the time its only about attitude and hustle.....they can evaluate skills. They came to see the Pitching prospect and end up asking about the hustling catcher...
If you got a prospect that's drawing attention...be happy for them, play hard for the team and go out there and show your stuff...... You never know who is watching and what their needs are.......you could be the one.
