Oh yeah. When it comes to high school baseball recruiting, I could write a tome.
It's a strange sport to judge. What separates great from good is consistency. And that's hard to judge in high school because good players often end up with the same stats as (eventual) great players. Also, it's a sport where physical size doesn't mean a whole lot, to a point.
Relationships are everything. Did your kid get on with Marucci in time to be their premier SS for the next three years? Did you play college baseball? Do you have relationships with college coaches because you played? These are important questions in the baseball recruiting world.
Camps are important, but only if the people putting on the camps have their eyes on you when you show up. Otherwise, the camps are mostly money grabs.
This is the ultimate networking sport. And if you don't have a network, here's what happens (from experience): Your kid struggles to get D1 offers, even though he is a three year varsity starter (hitting .400+ each year). He runs a 6.36 60, with velos to match. I know this is what happens, because it happened to us.
It's not sour grapes. My kid did end up playing D1. I won't be surprised if big schools come after him this year or next. It's such a different game from college football or basketball. Look at rosters across the sport. Players on their third school are the rule, not the exception.
