I also buy into the whole catcher to manager thing. Too many examples of it working.
You know, I was under the same impression about this. But having just gone and looked up Mgrs with the most wins, there's not a preponderance of catchers there. You've got Torre, Bochy, Scioscia, Houk, maybe Torborg and Ned Yost.
But among the guys who made more of a career out of managing than playing -- Alston, Sparky, Herzog, Tom Kelly, LaSorda, LaRussa, Cox, Mauch, Dick Williams -- none of them were catchers.
