It really doesn't matter, IMO, if he is just getting some attention, I doubt whether it would be enough to mean much, to be drafted to give up school.
Most of the guys drafted in very late rounds in sons organization are all gone, even some from last year.
I am not sure that most realize how much more an advantage is being drafted early vs.late (except a prospect falls due to signability). HS players after a certain round should not give up their college eligibility. JMO.
The above is probably correct,after a certain round the GM lets the scouts fight out whose guys will get called. I would assume the top scouts get their man (men).
