To be honest, there were some things about this that didn't add up, which I guess is why I posted here. I was not at that game, but was able to watch the kid this guy was "scouting" in a later game in the tournament. He did not jump out as DI material, to the extent you can even know that about a 15 year old. I would have dismissed the whole thing except the guy knew which high school my own son played for. There are maybe a dozen 15u players in our area that everyone knows will be playing DI ball in a few years, and my son is not one of them. Those are the only kids (if any) I would have expected a college "scout" to know by name right now.
I think you are probably right that he was with a service.
