Every Tuesday, The New York Times will look at the week ahead in the N.H.L., highlighting hot — or not so hot — teams and players. (All times Eastern.) Dallas Stars vs. Chicago Blackhawks and St. Louis Blues The West-leading Stars (25-7-2, 52 points) face their top Central Division rivals three times in six days, beginning with a home game against the Blackhawks (20-11-4, 44 points) on Tuesday. It is, surprisingly, the first meeting between the teams this season. That does not mean they aren’t familiar with each other; in the off-season, Dallas acquired forward Patrick Sharp and defenseman Johnny Oduya, key members of the Blackhawks’ recent Stanley Cup-winning teams.
