Do you really think a college coach and/or pro-scout can’t tell that your son has received instruction or not? If you reach the level where you are being evaluated by pro-scouts and college coaches I think it is presumed that you have received some instruction at some point. IMHO I think they can tell just how good that instruction has been. Another thing, I don’t think they give a horses-patoot.
Evaluating talent and ability, pre-performance, i.e. pro-prospect/college-prospect, is subjective. If you don’t have “it”, you will eventually be “found out”, no matter how hard you work, where you are playing, and/or who is giving the instruction. God given talent + natural ability + X-Factor + insatiable work ethic + the ability to adjust + opportunity, peppered with a little luck = HOF greatness. Mention the “5 tools” and we really have a moving target. But like the 5 tools, different degrees of ability and talent fit different programs, the economic reality of modern baseball, college or pro. Fungo always gets the grey matter workin’.
Worry about the things you have control over. Show up early, work your *ss off, and have fun. Who knows where you’ll end up!
