Yanks Should Sign Castillo, Not Trade for Byrd or Rios

Obviously, there's more of an unknown involved with Castillo, but there's also age and cost on his side.   Sure he might command some bucks, but he won't command any of the assets we're finally starting to accrue on the farm.  In fact, he becomes another young asset on a tradable deal.   Byrd or Rios cost control and the Yanks would be foolish to spend that on either of those guys.
