Catchers are really hard to develop and probably is the position with the highest variance outside pitching. If you can sign a bonafide catcher star like Realmuto it opens the door for trading Jansen, Moreno, Kirk, etc. in a package for a large upgrade in a position of need (or in the case of SS, a bilateral upgrade at 3B by virtue of moving over one of Bo or Biggio there). Cleveland would sure love to get their hands on one of our young controllable catchers.
