I feel like a lot of the negativity is just pessimism using coincidences to decide a future outcome. If you trace it step by step it's a couple of different things happening.
2021-22 season: Following the disastrous 2020 summer and the following 2020-21 season killing the good will from the 2020 playoffs, the team started demoralized for the 2021-22 season when Benning & Green were brought back yet again. The team had a huge bounce when they were all fired, Bruce was brought in, and hockey was fun again. Upon closer examination though, the team was terrible defensively - both in roster construction and in game plan, but were getting propped up by Demko playing lights out.
2022-23 season: Demko falls off, gets injured, and all the defensive issues are exposed. He's fired, Tocchet's brought in and starts implementing proper defensive structure, and the team rebounds playing well in the latter half of the season.
It's two seasons where the team started off poorly then rebounded after a coaching change, but in both cases the cause and change were different. The team came with a lot of problems for new management and this is knocking them off one at a time. It by no means guarantees success this season, any number of things can go right or wrong over an 82 game schedule, just saying the 'it happened twice so it will happen again' stance is needlessly pessimistic.
