What we learned from the past week in the NHL:
* Philadelphia Flyers rookie defenseman Shayne Gostisbehere, who wasn't promoted from the minor leagues until mid-November, is making a push for the Calder Trophy as rookie of the year. The Florida native has a 15-game point-scoring streak, a record for rookie defensemen and the longest by any defenseman since Chris Chelios' 15-game streak in 1995-96.
Gostisbehere has five goals and 18 points in that span. He scored his fourth overtime goal last week, tying the single-season record for OT goals by a defenseman set in 2001-02 by the New Jersey Devils' Scott Niedermayer.
