You are correct in your Arcia assessment that the Twins have always valued defense. But let's think back to Randy Bush. He played a total of 50 games in the field from 1982-1985 and never hit higher than .249. But he showed enough with a little power that, in 1986, and even to a greater extent after Tom Kelly took over, that they worked with him to become an adequate defensive player and a vital part of two World Series winners. Do we really want to trade Arcia and see his offensive potention be realized somewhere else? I think the Red Sox just called looking for an eventual replacement for Big Papi.
