say you've got an 18 year old draftee w/ great projections, but is still too raw to play in the upper minors, however you place him in AAA or the majors anyways, and play him every day. Even though he gets his brains beat in, will he progress as normal since he's playing everyday, or will his makeup suffer, or some other stunt in his development?
in other words, does having relative success at a level improve his rate of development, or does success or failure have little to do with, he'll improve at the same rate provided that he's getting playing time at the same rate?
