Kirk Gibson has been preaching calm to his team. He doesn't want the highs to get too high or the valleys to get too low. In his (extensive) experience, it's too easy to fall into a rut and let a bad game, a bad play or a bad call carry over to the next game or even the next at-bat.
You see that today after what really should have been a very exciting win for the Diamondbacks. Instead of a celebratory club house, the team put on the quiet, calm and determined demeanor of their skipper.
