I believe you should carefully consider what the scout told you, yet temper it against other evaluations. And this will probably sound obvious, but if your son is a D2 or D3 player at this time instead of a D1 player...that is still an awfully great and cool thing. Just ask infielddad and a few others on here.
Listen to any and all evaluations and focus your efforts based on the emerging consensus of those evaluations.
