The intent of ESPN’s K-Zone superimposed box is plain, to tell us if the pitch is a ball or a strike. Is that rectangle on our TV screen really, really the actual strike zone? But is it really, really adjusting for every batter? If the game is over and you have lost, I guess your win probability is 0 percent. The yellow first-down line is extremely helpful and extremely unobtrusive; the K-Zone box is extremely unhelpful and extremely obtrusive.
