Parents shouldn't assume that Head First and other high academic camps are wrong for kids who are not academic superstars. Yes, many if not most there are schools with low admit rates, but there are plenty of others that attend, like Washington College in MD, for example, with higher admit rates. 90% in WC's case.
See who's going where and act accordingly.
Also, don't assume that your player will only be recruited by coaches he's had contact with. Sure, emails and videos are a great idea, but a kid who does well at these events will likely end up being recruited by schools that are not even on his radar. Mine did.
