McDavid has nine points (two goals, seven assists) this series and an NHL-leading 23 (six goals, 17 assists) in 10 games in the playoffs."Maybe our focus has been a little bit too much on the Oilers and we've kind of started playing their game a little bit more than we've wanted to play our game," Flames forward Milan Lucic said on Monday. They've played really well in these first three games, so all our energy and focus has to go into finding our game, and when we do that, we give yourselves a really good chance to win."Calgary was the third-best defensive team in the NHL this season, allowing 2.51 goals per game.
