The idiot neutered his best and only real scoring line by playing them against Bergeron and Marchand all night long.
Not to mention setting Marchand loose against Eichel and Skinner.
This is remedial coaching... you have last change, you don't put your best players against their best defenders.
Phil is an idiot and should be gone immediately.
I haven't looked to see if the zone start numbers corroborate this, but, if true, this is pretty damning. That's one of the best lines in the league centered by, what, a top-3 defensive forward in the game...and you go looking for that matchup for Eichel and your two best other forwards? Yikes. That's a matchup Boston loves - and one they'll try to get when the games are in Boston - and you give it to them.
The loss of ROR is going to sting for awhile. No NHL coach is scared of Casey Mittelstadt (for now) or Berglund.
