The Calgary Flames are on a three-game losing streak and have lost five of their past six games. "Things can be frustrating at times," forward Sean Monahan said. "Things don't always go your way. It's a long season. As a group we have to work harder and make those opportunities for ourselves." The Flames have scored eight goals in their past six games. Johnny Gaudreau, who had one goal in his previous nine games, scored twice in a 4-2 loss against the Dallas Stars on Thursday. Monahan, who centers Gaudreau, hasn't scored in his past six games. "I know I've got to be better," Monahan said. "I'm not happy with my game right now. I've just got to continue to work hard and find ways to figure out my game." Calgary's power play is 30th in the NHL (8.0 percent) and they are the only team in the League without a power-play goal on home ice this season (0-for-26). "If you're not getting it done on the power play, not scoring goals, it can be frustrating," Monahan said.
