I found this article by Sports Illustrated’s Tom Verducci to be very thought provoking regarding the “pitch count” mania that has overtaken major league baseball and has filtered down to the lowest levels i.e. Little League. Pitch counts are really akin to weight restrictions on bridges. If there’s no attempt to make the structural part of the bridge stronger then there can’t be an increase in work load.
Quote: "The system guarantees diminishing returns: Despite advances in medicine, nutrition and training, teams work pitchers less than ever before and yet pay them more. "
