Sorry Stardad, dreaming that your son can someday get AROD kind of money when he's only a freshman is not reality. I don't care how much of a rookie you are at this we all were at one time or another.
You can't compare your son to Max Sherzer, who was drafted out of college, not HS. What you need to do is wait until a year or so from now, take him to some national showcases or tournaments and then you can make conclusions as to how he compares to the rest of his HS grad class, not now.
I hope that you do not convey your thoughts to your son. Some folks do this and when their players don't make Arod status, they end up all messed up.
