If you happen to think Yasmani Grandal was the Dodgers third choice as a catcher in the offseason or that he is only here until the Dodgers find someone better, then I have to conclude that you have been misinformed.
Did the Dodgers HAVE to trade Matt Kemp? Of course not! They tried to get Russell Martin and Miguel Montero first, but it wasn’t because Grandal was their third choice – it was because they would rather have traded Ethier and Crawford than Kemp. Yes, they got some salary relief by trading Kemp, but they would rather have kept Kemp with Martin or Montero.
