We had one. The conversation went well. Son attended their pro day before draft. In the end while we and he were up for the possibility of the draft, i believe college was the better option and the team's valuation of him wasn't quite in sync with what our number was for bypassing college. Ask lots of questions about typical day in the life of a MiLB player, bus rides will be brutal, medical support, college fund is another area they will reinforce to placate the parents who are concerned about education.
It has worked out so far but the visit and attention for him was a cool experience. College was definitely the better route for my son as the maturation aspect is a huge factor for an 18 year old considering the draft over college.
