Baseballpapa I assume we're talking about your son here?? Seeing how he's 18 year old can we assume he is a senior and has committed to a college? If so how did they find him?
I don’t have a lot of experience in this area (most parents don’t) but I’ll give you my take. It’s difficult to determine if your son is well known in the ranks of professional scouts or not. They can be a very tight lipped group. Most of the time they know more than you think. Professional scouts can be very aware of players .... they just don't go public with their information.
You say that your son's velocity has never peaked? As a parent I tend to believe all parents will always see that underdeveloped potential in their sons. Human nature.
The draft is a very unpredictable event. MANY professional people devote most of their waking hours trying to predict the “future” of the draft with mixed results. It’s next to impossible for a parent like you or me to follow our sons into this experience and project the outcome. You need to go through the motions of a good summer team and showcasing your son’s talents and everything will fall into place .... We just don’t know what that “place” is.
