The Philadelphia Flyers have surrendered four power-play goals in five attempts over their past two games and defenseman Matt Carle thinks he knows what's going on. "I think it just comes down to [the fact] we're getting the opportunities to clear pucks and block shots, and we're not doing it - and it's really been killing us," Carle said, adding that the Flyers need to be more aggressive and not sit back as much on the penalty kill. "It seems like we're always playing from behind," Carle said. "I can't remember the last time we scored the first goal in a game, and that's been the biggest thing that's killed us. It's one of the things we need to iron out as we come down the stretch."
