I don't think Pablo was a factor here. The Red Sox traded Moncada because there was absolutely no way to get Sale without giving up at least one of Moncada or Benintendi. If the White Sox wanted Devers at all, and they might have, he clearly wasm't a "must have," as they were willing to take Kopech and/or Basabe instead.
In fact, Devers still doesn't impress me much. I just can't get excited over anyone in A ball. Let's se how he does this year in AA. Personally, I have more faith in Longhi this year...
