I can't speak for the others but I will share my point of view.
It's easy to criticize when the team loses and much harder to do it when winning. The guys who deserve praise (i.e. Woll, Knies) should get it but those who don't shouldn't be getting lumped in with the rest. Of course, a lot of things get masked over and everyone looks a million bucks when the team wins.
I was praising Marner for his work in game 5 where he showed he can play well against the same team. In fact, this makes him reverting back to his bad habits even more frustrating.
To start with the issues, Marner is a part of the reason the PP blows. Rielly is the biggest offender but Marner is next up with Tavares.
Marner was good in game 5 (especially 1st period) but in game 6 went back to his bad habits again. A few good plays but also some terrible ones. We can accept he has helped stop their best offensive players but he's also been completely shut down by a Bruins forward group that doesn't have Bergeron or Krejci.
Marner is not a defensive winger. He's paid to get points, generate offense, and yes do good defensive work alongside the playmaking. Right now with Matthews out, he's supposed to be the #1 guy on the ice. Someone posted the numbers before game 6 where Kampf was doing a better defensive job against the top line in the minutes he played against them compared to Marner, so he's not even the best at that aspect right now.
Kampf gets paid less than $3M. Marner gets paid $11M. They should not be doing the same thing.
Marner is supposed to be playing like a superstar out there not as a defensive specialist.
