One thing that I think is important but is mostly overlooked is the age of HS prospects. In many cases, HS guys rated highly are not only late in the year 18 YO but for some, actual 19 YO. There's a trend around the Country where parents hold their kid back a year on purpose to get an extra year of maturity on their peers. And it works most of the time.
Because of that, I've given extra credit to HS guys who are young for their class but still top prospects. There's a good chance that with additional development that time alone brings they will be an even better prospect than they appear at draft. That's one of the reasons that I was so high on Gorman last year. He was a top ten guy who was extremely young for his class. I was also not very high on Blake Rutherford for the inverse. He was old for his class but wasn't a slam dunk star.
This is really just an extension of the thinking that used to concern everyone about international FA - how old are they really?
With HS guys, you know. But it's just not focused on in evaluations that much apparently.
You can extend that to College as well but not as much. If a 23 YO Junior still has questions, then chances are those answers are negative. If a 20 YO Junior still has questions, there may be development time ahead for positive answers.
