I'm going to take some blame away from Bones, but I'm also going to not give Bones credit where it's not deserved by refuting 2 things you've said.
Reese makes the call on goaltending. Bones has been clear about that from the beginning. Reese also had a really good track record as a goalie coach. While it does amaze me that Oettinger had only played 3 road games prior to that Colorado game, and I at times thought that was insane, the way Reese has managed Oettinger has brought us to this point that I don't think you can say Otter's the 1A option right now. In the past week, he's the clear #1 goaltender on the team, and it's his job to lose or hold on to. Goaltending is baffling so yeah I felt like the decisions seemed really odd, but there's also a part of me that doesn't want to argue with the results if they've created what we're seeing right now. However we view it though, those decisions have been on Reese and not Bones.
On the other hand, it's utter crap that Bones doesn't have options. He's refused to explore them. Nill deserves blame for the cap and roster make-up for sure, but he also deserves blame for allowing the coach to refuse to play depth players. Nill waived both Comeau and Kero to give the team a chance for younger guys to help with secondary scoring, and Bones refused to play them. Regardless of who the player was, they either played a handful of minutes or remained scratched. Despite being 6th in goal scoring, Peterson is a 4th liner.
When it comes to depth scoring, it's up to those two to figure out a solution. Apparently, a coaching change was considered, and Nill didn't pull the trigger. That was one option getting a coach that would put players in a position to improve 5 on 5 scoring. It's on Nill now then for not getting a player that Bowness would be willing to trust in that role. They're both screwing this up and making bad decisions when it comes to making an actual tangible positive impact on the team. Who you choose to blame seems to depend on which guy you favor a bit more because it's not one or the other. They clearly aren't on the same page about how to correct the issue. They're both deserve equal blame.
I'm not even suggesting that it MUST be fixed. If it's not, I'm fairly confident that they'll be out in Round 1 if they make the playoffs, and at minimum 1 will be gone and there's a good chance both will be gone. Their entire identity right now is basically winning because of goaltending, the PP, or the 1st line. I think the only thing that actually frustrates me is Gaglardi and Nill claim they're built for the playoffs and they believe in this team, yet winning in the playoffs requires 5 on 5 scoring and you've done nothing. You've had a pow-wow about changing the coach, decided not to do it, and you're not doing really anything to improve scoring so far. What you're saying publically doesn't match what you're actually doing.
