At this point, I have no idea what you're talking about. Of course I don't think they're trying to underperform. But they are, they look awful, and I hope you're not trying to blame that all on coaching and management.
The young players, particularly Duchene and MacKinnon, need to learn how to play well when there isn't as much space. If they don't do that, this team won't go anywhere. Teams have scoured the Avs and they're taking away their space. Those two have to adjust.
Duchene has two shots in the last two games, after their coach has been preaching to stop the fancy play and put more pucks on net. He needs to figure it out
Roy wanted the team to not rely on creating space with speed. So he brought in players to try to ensure that. This is why the two old guys are leading the team in scoring. Roy made a conscious decision to make a stylistic change and he's gone so far to shoehorn this slower stationary style into the offense that they no longer to have the complimentary personnel to create in transition.
Oh but let's just ignore this and mindlessly say the two most talented players on the team suck even though they're also the two most prepared and dedicated players also.
Last year Duchene had OReilly playing for money as a line mate. This year that line mate is in year 1 of 2 and is pouting over money. And with Duchenes and RORs past bad blood, they should have known something line this might happen. But the front office was too obsessed with being right in arbitration, that they weren't smart enough to see all the ways they could lose by "winning". So instead of upgrading Duchenes line from last year, Duchened line has been diminished.
Same with MacKinnon, except they let Stastny walk--and for nothing.
But let's just blindly defend Roy and blame the players. I mean, they are the ones making roster decisions that affect team chemistry, right?
