Attempting to Rationalize the Shelby Miller Trade
With the title of this post, I have given myself an admittedly difficult task, given most comments about this trade since it went down. Arizona traded two top-100 prospects, including one player in the top 25 (at least), as well as a proven major league outfielder in exchange for a somewhat inconsistent pitcher, albeit one coming off a three-win season and with three more years of control. For the most part, everybody is beating up on the Diamondbacks — and for good reason: we don’t know the internal valuations the Diamondbacks possess on their own players and players outside their organization, but there is a general consensus that whatever those valuations are, they do not match up the rest of baseball. As a result, they have undersold their assets compared to the rest of the market. If we take out the external valuations of players like Dansby Swanson, Aaron Blair, and Ender Inciarte, can we make a case that, internally, the decision might have been sound?
What I am trying to get at is this: the trade value on the open market for Dansby Swanson, Aaron Blair, and Ender Inciarte is much greater than one Shelby Miller, but if you are the Diamondbacks and presented one choice and one choice only, how do we get to a spot where you choose Shelby Miller over Dansby Swanson, Aaron Blair, and Ender Inciarte?
