Wait are you serious?
Potentially quite a few!
As for the rest man I just don't agree. Of COURSE a lot of it is on the players. They are old and this roster has problems in it's construction. But who has had a big hand in putting this roster together? I know I'm talking to the guy that thinks that the GM stays entirely in his lane and the coach in his because of the titles next to their name but I don't know that you'll find many that agree.
This is Mike Sullivan's team. If you hate how the players are playing... he picked 'em. And if they are just out there dogging it... how is that not on him?
What DOES this guy even do in your personal estimation? Besides scoop all the glory when they ARE winning?
1. Firing Sullivan midseason likely gets them 8-10 points. Max. Which puts them right on the bubble of making the playoffs and does nothing to alter their long-term future. Again, it's better long-term to fail this way.
2. Sullivan absolutely had a hand in this roster. Roster construction is a collaborative effort. A good GM works with the coach to acquire players who fit the way the coach wants to play, and this roster is the most geared toward Sullivan's preferences in years. I think it partially matches Dubas' preference, but he'd make some additional changes, which I think we'll see over the next year (I don't think it can happen in one offseason).
3. As much as this team has struggled, I don't think effort is an issue. They're not dogging it, with maybe one exception (Smith).
4. Sullivan's best attributes are locker room and player management. He's routinely praised for how he handles the locker room by players, how he manages their focus and attention to detail. I don't think every player likes him, but the vast majority respect him and appreciate his communication level.
5. I think he's an average coach from a schematic standpoint. He has some ideas and has shown a feel to adapt on occasion, but he's not an innovator. I think this has been a primary issue the past two years. He's out of ideas. He doesn't have a solution for the power play to override anything Reirden proposes. He doesn't have an answer for 5-on-5 play.
So, that's what he does. He's a personnel manager with some Xs and Os thrown in. I think the players still respect him, but I think he's out of ideas.
I also firmly believe that this is not the kind of team that responds well to a midseason coaching change. Edmonton did because it served as a wake-up call for a team in its prime. It's too early to judge any substantial impact on the Kings since their coaching change, but they likely were never as good as their start to the season suggested and they're closer to their real talent level now (fringe playoff team).
The Wild, Islanders, Senators, Blues and Devils are all likely missing the playoffs despite their changes. Travis Green isn't leading the Devils back to glory, that's for sure. And these are examples why I think midseason coaching changes are overrated. You get a temporary bump - maybe - but a team often just falls back to its talent level. And in this case, the Pens are better off long-term being forced to sell at the deadline and hit the reset button in the offseason.
