It has to be pointed out that the Bruins play their stars way less than any other team, so I think in that sense the Bruins depth gets underrated, even though it hasn't translated to production for anyone else so far this year. The biggest offensive stars in the game are getting 17+ ES minutes and up to 4 PP minutes per game. The Bruins trio is hovering around 3 PP minutes per game, but their ES TOI per game is:
Pastrnak - 15:13
Marchand - 14:24
Bergeron - 13:43
Bergeron and Marchand are regularly the top PK duo.
The PP time is just because they score so quickly
