Despite sweeping a home-and-home series against Ottawa last weekend, the Canadiens once again find themselves trying to hold off the Senators to remain in first place in the Atlantic Division. Montreal, which has seven games remaining, has 91 points for a one-point lead on the Senators, who have eight games to play. The Canadiens led Ottawa by four points following their 4-1 win at Bell Centre on Sunday, but Montreal lost 2-1 in overtime to the Detroit Red Wings on Tuesday and 4-1 to the Carolina Hurricanes on Thursday. "I think for us, our main concern is that we're playing with the same effort every night, and I don't think we had our best [Thursday] and it's got to get back to where it was," defenseman Shea Weber said after practice in Brossard, Quebec, on Friday. "I thought on the weekend it was desperate hockey and that's the way we need to play again [Saturday]." The performance in the loss to Carolina was unacceptable to coach Claude Julien. "We have to be a lot better and there's no doubt that that game [Saturday] has something at stake," he said Friday, "so there's no excuses for not being ready to play and not being willing to be better than we have been the last two games."
