I think that you got good advice above.
I would just sit tight and enjoy the ride. You will know if there is serious interest for the early rounds. Or you may not know until draft day for a later round pick.
The important thing is that it should not be a distraction and unless someone hands him lots of money, go to college.
When son was drafted, 2nd round he went to play in the NY Penn league, better known as the college league. He twisted his ankle so they shut him down sent him to Jupiter, he pitched a lot his junior year and they knew he needed some time out, but he was 21 going on 22 with college experience behind him.
His roommate was a HS senior who accepted 10K as a late sign. He cried himself to sleep every night. It's not fun getting up early and playing games in the backfields of the complexes, which HS drafted players start out with the Latin players who speak no english. Done at 1pm everyday a young man of 17, 18 can get into a lot of trouble.
Don't mean to be a downer, but it's not what everyone thinks it is getting drafted out of HS unless you have a big support system which includes an agent, a financial advisor as well as athletic sponsors and free gym memberships.
