When you start drafting for need, at a "position", you are either saying that the major league team is well stocked for the future or the system is well stocked to provide for a well stocked major league roster(either through promotions or trades).
I doubt the Reds are at that point yet, though we could maybe make a arguement unlike going into 2004 when it was easily clear things were in shambles.
I would still draft based on talent, rather than a position of need like catcher for another year or two.
