Baseball managers, it seems to me, have it rougher than the coaches and managers of other sports. They are, in so many ways, prisoners of chance. The perfect pinch-hitter at the perfect time still fails most of the time. The lousiest reliever will, most often than not, get the out. A stupidly constructed lineup might score 12 runs one day, a brilliantly constructed one might get shut out the next. The in-game moves simply don’t impact the game the way they can in other sports, and the best baseball managers probably do their best work behind closed doors away from everything.
