I don't know if Dave Roberts is a genius, but I do know that w/o him being available to pinch run for Kevin Millar, the SOX probably lose to the Yankems in game 4 and, of course, no 2004 championship. I'll always admire Dave Roberts.
There must be something bad that happens during the game that is the manager's fault. I remember Joe Torre once said when he was managing the Yankems, "I just make out the line-up and then I get out of the way."
