We keep bringing up prospects who can't defend a position. I also continue to read minor league reports of players playing C, OF, 1B in the space of a week. Do other organizations shuffle their prospects from position to position? I'd like to think by the time you've promoted a prospect to AAA you'd figured out where he fits on D. An earlier poster pointed out that repetition is key to improvement. Constantly changing position with these guys cannot be helping their development.
