I'm seeing less and less of a reason to believe that this team is anything but exactly how they've performed this year.
The bottom-6 is doing what it is designed to do, they're getting exactly what they want out of that bottom-6 (low event defensive hockey). The issue is that the top-6 can't consistently score enough where a low event defensive bottom-6 works. You're not winning many games in the NHL if your top-6 is only putting up 2 goals a game, your bottom-6 can't produce and your powerplay doesn't work. That structure works if you're Toronto and have a prime aged core of Matthews, Marner, Nylander and such in your top-6. The Penguins have a late 30s Crosby and Malkin along with some complementary wingers.
That's not me blaming the top-6, it's that the fundamental structure of this team doesn't work because the top-6 isn't as good as Sullivan/Dubas thinks it is. The core players are no longer good enough where you can win games without getting depth scoring, nor is the defense/goaltending good enough to make up for that either. At the same time, you're spending so much money on the top-6 that you don't reasonably even have a way to help the bottom-6 production. I just don't know what you can even do with this team.
