Anyone remember the story about McCarver going out to the mound to talk to Gibson. Gibson told him, "the only thing you know about hitting, is that you can't hit. Get behind the plate". I know I took liberties with that, but I can't remember it for verbatim. My apologies.
You know Justin Morneau came up as a catcher. He developed into a pretty good first basemen. He credits Tom Kelly as the man who taught him the proper footwork and positioning.
