I don't know, John, but maybe I'm more suspicious: how do we know that you're not just spying so as to become a more effective, uh,
advocate for your own team?
But seriously: I wonder whether you had any trouble changing your focus to that of an umpire. Coaches and umpires see plays differently, after all, and your habits must be those of a coach. Did you ever feel that you didn't see what you needed to in order to make a call?
