We have a better team than we had last year (or similar at least).
This drop is purely on the coaching staff.
I don't think it's that simple to just blame the coaching for the drop off from year to year. The top end on the forwards is better, but the depth is worse, the defense is worse, and many of the players are executing worse (and the goaltending has mostly been a mess but that is what it is).
The injuries and the games lost to goaltending early have resulted in a lot of players forcing and getting frustrated by what came naturally to them last year. That's brought down the execution and the mistakes we just weren't making last year. The loss of Severson and Graves reduced both the overall experience and experience in the system of the D. Bahl played this system on and off, but not regularly until last year. Luke played it for a few games last year. Nemec never played it. All 3 of them are also still in their first or 2nd years of NHL experience and only Bahl has more than a year of Pro experience. Marino has not been quite as steady with Bahl instead of Graves. Severson has been sorely missed in several areas. The lack of PK D forced Smith into the lineup more than we want.
The drop off with the D affects everyone else. There are fewer layups from 2 on 1s because the D isn't as sure to get the puck and start those. The forwards trust the D and goaltending a little less and are quicker to drop back so we can't overload as much in the offensive zone. They also start trying more shit in the defensive zone because the puck isn't getting out as quickly with as much control. We had to make these moves eventually, but you can't write them off either. It's better to happen now than in the future. The goaltending not being an absolute sieve to start the year would have helped prevent some of that confidence from eroding as well.
If you want Ruff fired that's fine, I don't think he's the best coach in the league or anything. But I think it's unfair to pin this all on coaching. I also think, all things considered, we've played better than our record to this point in the year. Maybe the results swing our way at some point and maybe they don't, but I think this team deserves 3-5 more wins at this point than it has and that would change the optics.
