c2019, for most, when they get these links, the primary purpose is moneymaker for the school. But, as I'm sure you are figuring out by now, there isn't a school in the country that wouldn't be interested in getting a free initial look at a freshman who throws 89. The possible exception would be if your son is not up to academic standards for a given school.
Someone mentioned that the player should be driving the process and making the contacts. This is very true. Someone else mentioned that your son is probably too young to handle those things. This is also probably true. So you have a situation where you have to be careful. Just be aware that it can be a big red flag to an RC that a dad is contacting him instead of the player. Even as gifted as your son may be, you don't want to put out negative impressions.
