My #1 draft pick this year ended up being a 22 year old-- is it wise to start him in rookie ball like I would an 18 year old, and progress him basically the same way (AAA by the time he needs to be Rule 5 protected) ? My best pitching coach is at High A, but my coaches at RL/LoA aren't terrible, just average.
The prospect in queston is starting at 63 ovr.
Any tips?
