Bruins defenseman Zdeno Chara was the image of serenity lounging in front of his locker at the conclusion of yesterday's short practice at the Wells Fargo Center. The source of Chara's calm was his steely sense of anticipation. He sees a Category 5 storm in the forecast tonight when the wounded and furious Philadelphia Flyers take on the Bruins in Game 2 of the Eastern Conference semifinals here. "We know they are going to be better and more physical," Chara said. "They are going to be very hungry, they are going to come out really strong and ready, and we have to just focus on our game and play hard." "We want to play a strong game and we know Philly is a really good team with all the elements. We have to be on top of our game because they will be coming after us very hard." Chara and defense partner Dennis Seidenberg were on the ice for most of the Flyers' foibles in Saturday's humiliating 7-3 loss to the Bruins in the series opener. Chara played 28:08 on 34 shifts and had two shots, two hits and a plus-3 rating. Seidenberg was also efficient over 25:43 minutes on 30 shifts, with four shots, two hits and an impressive plus-4. Seidenberg was more active than Chara in the offensive end. Seidenberg's risky trips deep into the Flyers zone produced assists on the Bruins' first two goals, by David Krejci and Nathan Horton, respectively. Bruins coach Claude Julien commands a defense-first operation and he has come to trust Chara and Seidenberg to make calculated, situational adjustments. But it was obvious that Chara and Seidenberg were prepared to take more chances against the Flyers than they did in the last round against the Canadiens. "I thought we just reacted to certain situations and we were able to jump out and help the offense a little bit," said Chara. "That's not the style we play; we try to focus on good defense. "But if there is a chance and the timing is right, you go. Dennis was in a situation where he was the closest man to the puck and his position was covered, giving him the freedom to go make a nice play both times.
