I liked Riggleman before his temper tantrum. I think he was pretty good about making common sense decisions. He was your typical MLB manager.
Love Davey. Even though I may not always grasp the intricacies of his decisions or even notice them, I do trust he is winning the battle against other managers.
Riggleman managed games. Johnson manages the season. He's playing chess when most managers are playing checkers.
Right now there isn't a manager in the playoffs that will do better than Johnson at putting guys in the best possible spot. Just comes down to them doing their jobs.
