i really wasn't going down the path of getting an advisor. Advisors can be tricky; not only may a kid run into NCAA issues if one of the mines in the mine field is triggered, but the advisors are hoping to become agents (the primary difference is an agreement which entitles them to a small portion of the players money) and, therefore, tend to tilt towards pushing a kid into pro ball sooner.
I was alluding to the weighing process of the myriad of elements which go into a decision to pass up college and head directly into proball. Every couple of years a thread will discuss these elements. There is no right or wrong decision, per se. There is a right and wrong decision for each individual player (in other words, the same elements will be weighed differently by each family thereby leading to a different conclusion for each family).
Once the spring HS rolls around the circus begins; dozens of scouts at games, cross checkers, and even higher big wigs will pepper the crowd. All those parents you've grown older with during youth baseball and travel ball will watch with envy; your son may begin to show signs of stress (in the classroom or in the field [thinking - wrongly - that a bad outing/pitch will torpedo his chances]); you will get sucked into that vortex. At that time it is possible to lose perspective (in the short run; but it's only a short run until the draft at that point).
It become very difficult to keep your priorities in order (basically education v. Proball). So, begin thinking about those issues now - before the dreams your son has had for a decade seemingly appear at his fingertips.
Advisors, scouts and even instructors and his coaches may have the priorities in a different order then does your family.
It it is pretty clear that your son will - absent unforeseen problems - have a choice to make. While it may ultimately be his choice, he is a 17 year old who has no context within which to make this choice. And this choice is life altering (whichever way it goes). That is where a family really matters - the family's collective wisdom helps decide what are the priorities. The time to begin thinking about that is now, while it is relatively quite and calm; in six months your family will be buffeted by some very strong forces.
