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. I think the vision of this team, both from the system Sullivan is running along with the roster construction that Dubas selected, is just fundamentally not correct on the evaluation of the core. This team doesn't have the ability to run the system Sullivan wants to run, nor is the core good enough anymore to be able to win games with a completely unproductive bottom-6. The fundamental vision of this team is based on the flawed assumption that the core is good enough for the vision to work, it's just not anymore.
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. Firing Sullivan is really the only thing I can see that even might make a difference, but I still don't think that would move the needle substantially.
If they'd fire Sullivan the results didn't improve, I'd be fully ready to just write off this team as being past their prime and done.
