This just makes zero sense. Let's take Hall, who plays other positions, and put him at short. Then, move JJ, who hasn't played anything else in his life, to 2b? The difference in range is not going to make a huge difference over the course of the year. You're making things harder than they need to be. Besides, this is all happening in fantasyland. JJ Hardy IS the Brewers SS, regardless of what you'd like to see happen.
