The NHL coaching changes have begun early this season, with the Boston Bruins parting ways with Jim Montgomery after a disappointing start. Despite high expectations, the team has struggled offensively, relying heavily on David Pastrnak and Brad Marchand, while new acquisitions Elias Lindholm and Nikita Zadorov have underperformed.

Interim coach Joe Sacco will attempt to rectify the situation, but the Bruins face significant roster challenges.

Meanwhile, the NHL Power Rankings highlight standout performances, including Martin Necas' impressive scoring streak and the struggles of teams like the Penguins and Flames.
