Nice post, but are there any reasonable people suggesting that Pierre is more valuable than Dunn? Suppose Pierre can be acquired for one out of options pitcher, one Rule 5 eligible pitcher, and one other pitcher in neither of those categories. Suppose Dunn will cost Pie, Hill, Pinto, and Wuertz. Which is better for the organization? You may say Dunn, but that's arguable, whereas Pierre>Dunn is not.
