Arcia certainly is below average and looks clumsy, and Sano is athletic, but I have a hard time believing Sano will be a *better* defensive outfielder than Arcia. Did we not see in 2014 that learning to play outfield is more than shagging fly balls during BP? Arcia (all while looking clumsy) has a strong, reasonably accurate arm, makes plays to his glove side, backs up bases, etc., he also makes the occasional out-of-range play. I have no confidence whatsoever that Sano will do any of that consistently. I don't think Sano's 100-150 OPS advantage over Arcia would compensate for any of Sano's future crimes in the outfield, though I admit Danny Santana improved quite a bit over the course of 2014. However, an .825-.875 OPS from a near full-time Arcia would be pretty good to have, with or without Sano. And I do grant you that Sano is long term more important to this franchise than Arcia, and the temporary outfield experiment worked with Miguel Cabrera just fine. My understanding is that Sano in the outfield is temporary until Plouffe is on another team. Part of my angst with Sano in the OF all goes back to general roster construction, too.
