To me it makes little sense to have guys drafted out of the SEC, ACC or other power conferences to ever go to rookie leagues except for a wood bat tune up, and even then I don't see the issue with adjusting to wood bats in A ball. I'd also bet lots of GMs feel the same. But most organizational players don't get demotions, they get released and I'd also guess that the rookie leagues are much more likely to be filled with players who appear certain to washout. Meaning there's rosters to fill in the rookie leagues and the higher up you go, the better players you have to cut loose. There probably are teams (maybe this one) that are conservative or hesitant or coddle guys or whatever way we like to describe it. But most teams still do it and we don't view all teams in these terms. So I'd guess it's systematic. Though I'm usually for trying something new.
