The Bruins had a tall order to fill last night: Win the third straight game of their second-round series against the Flyers, and their first at TD Garden. They badly needed a power-play goal, an increasingly embarrassing void, even as the Bruins were playing their 10th game of the postseason. They needed to show the home crowd they were not going to lose their focus against the Flyers, the team that turned the tables on the Bruins last season, turning Boston's 3-0 second-round series lead into a 4-3 Philadelphia victory. And when they called on the captain last night, Zdeno Chara filled the order. He got the first goal of the game and he got the last goal of the game. He broke the team's 0-for-30 power-play drought with his second goal. He added an assist on Nathan Horton's second-period score, he was plus-4 in 28 minutes and 12 seconds of ice time (second only to Dennis Seidenberg by four seconds), and he took five shots. Chara was in on everything as the Bruins pounded the Flyers, 5-1, to take a 3-0 lead in the series, but after the game, his focus was still dead-on.
