Not sure what change is needed. Nor how missing the playoffs will help answer that question.
I'm assuming they will have a new full time coach next season. A new system to go with it. But that's no guarantee to work. I'm certainly not up for a complete, 5-year plan rebuild that could turn into a 10-year drought.
We differ on this. I'm totally here for a full rebuild, even while fully acknowledging that the odds are high that the whole thing will end in failure. I enjoy the process, the chase, seeing kids emerge and develop, the sense of unknown. Much prefer that to staggering on in mediocrity. Been ready for it since 2021. Then Monty's first season happened and I thought my forecasting had been wrong. Turns out it was instead perhaps just premature. For all that, don't begrudge Sweeney trying to keep the party going, because despite how it ended the 22/23 season was a hell of a lot of fun.
But that's past now, and the reality of the slump that almost all franchises have to go through post a long run at/near the top is finally upon us. So what next? Can a new coach, system and roster shakeup alone turn this team back into a true contender? They will most likely try, but I'm very doubtful about it.
As to preferring to miss playoffs, it doesn't make any major difference, I agree, just think it will force management's hand a bit more in having to make some bigger/deeper changes, potentially including within the front office. Less scope to kid themselves that things are more or less ok.
