I have no idea how you can blame this FO for what Buxton (hurt) Kepler (bad) Polanco (hurt), Sano (come on, no one has claimed him even) turned into.
And, they turned Arraez into Lopez and two minor league players. It was a fair trade, even if it hasn't worked yet. So that leaves Rosario, who was DFAd by CLE at one point....
Also, we should maybe give them some credit for developing Arraez....And, you are right on Jeffers.
