No one is suggesting that trading Dunn for Pie would be for defensive purposes. Are you suggesting that Pie can't hit? Certainly the chances of Pie being an above average hitter are much greater than the chances of him being a complete flop, right? How does the sentence, "a gold glove caliber fielder who can't hit is worthless" apply to this discussion? What I am suggesting is that a left-fielder with a .930-.950 OPS and not much else who is about to become very expensive pales in comparison to a gold glove caliber center-fielder with a .860-.890 OPS with great speed on the base paths who is 5-6 years younger and still has many seasons at or near league minimum. It is absolutely accurate to say that Pie may not ever become the player I described above. It is also absolutely accurate to say that he may. It would be great to have a discussion/debate about the chances of Pie fulfilling on his potential. Remember, at age 20, Pie put up an OPS of .903 in 240 ABs against AA pitching. At the same age, Dunn had an OPS of .897 in 420 ABs against High-A pitching. I'm not saying this is conclusive evidence that Pie will be as good or better than Dunn with the bat. No way. Only that this is one piece of statistical evidence that shows that it is possible. Dunn exploded the following year. Pie would have to take it to the next level as well. But if he can refine his batting eye, what are we looking at? If we didn't just trade for Pierre, I'd agree with you. After the price we paid to get him, Pierre will be getting a multi-year deal. Pie loses a lot of value in a corner OF spot.
