By NCAA rules colleges weren't able to contact him until September 1 of his Junior year which was only a few days ago. He has been contacted by 6 different colleges. All said they were interested in him being part of their program but none offered a scholarship which can only becomes official at National Signing Day of the players Senior year. One pro scout told his travel Ball coach he would arrange a tryout for the Area Code Games next summer. We figured getting this much contact the first month was pretty good. I'm sure if he's good enough he'll get an official offer once he starts his Senior year.
Per NCAA rules, a team can be contacted by the player from the time they take their first breath. So, if a college coach sees a player they like prior to September 1 of their Junior year, they reach out to that player’s coaches (club or high school) and tell them to call them.
Teams can offer a 9 year old if they want, age has nothing to do with it. Offering a scholarship and verbally committing are a component of finally getting to the National Letter of Intent, but you won’t get to sign that NLI without an offer and a verbal commitment prior to that. That’s just how it works.
Hopefully your son has a little clearer picture of how this works, because this is an important year for your grandson, and you seem to have an idea of what is going on, but you need a little clearer understanding of how this plays out.
