I'd also check out how they promote players. I see tons of guys who really don't have contacts post the same boilerplate post about the kids in their program. Then I see guys promoting the heck out of their kids, tagging coaches/people with influence, telling parents "hey, get this on video for me to post", and inviting them to participate in an event or practice or something where a college coach will be watching.
One thing I noticed with the coaches of my son's team is when they take kids to a showcase they are working with them through the showcase. The catching coach had the kids doing catcher drills to prepare for their pop times and even coached them during the event if they did something wrong.
I guess what I'm getting at is see if you can get a feel from kids/parents on the team if the coaches genuinely care about their players AND has real contacts.
