Do you think Moustakas would be better? Beyond the "click bait" part of my title, the main point was to put Arcia in a position to field a higher percentage of balls than anyone else on our infield. 90% of Arcia's value is in his defense. So I'm advocating that with an infield of Shaw, Arcia, Moose, and Aguilar/Thames, I'd put Arcia wherever the metrics say he will get the most balls. Among those 5 players, he is by far the best defender at SS/2B. And probably 3B/1B too. I've read comments from Counsell that the defense is based on Arcia anyway so I wouldn't be surprised if they already plan on doing something like that.
