David Krejci went home after the Bruins' win Tuesday night over the Ottawa Senators at the Garden feeling pretty good about the progress his struggling game had made. Then the center thought about how good he could have been, and the tossing and turning began. "Yeah, it was tough to sleep after the game because I could have scored three or four goals," Krejci said following yesterday's morning skate. "During the game and after the game, I was happy, we won and I felt I had a pretty good game. But later at night while I was laying in bed, it was tough to fall asleep when you know you had so many chances and the puck won't go in the net. But I felt good on the ice." Well, Krejci probably slept well last night. After coming into the game with just one goal, no assists and a minus-6 rating, he notched a goal and two assists, and was a plus-3, in a 7-0 B's rout of the Maple Leafs at Air Canada Centre.
