I think there needs to be a dose of context and realism applied to that edict.
If a team finished with 60 points and has a weak or aging core of players, then I think the focus should be on 'building' > 'playoffs'. I mean, you could trade your first round pick for a good vet, and deal some youth and prospects for decent NHLers, and maybe finish with 75 points instead of 60 but in the end you've harmed your ability to be competitive in the future.
Now granted we weren't anywhere near that scenario in September so I don't *blame* Linden/Benning for targeting playoffs, but I do think we are nearing the point (or are already there) where the focus has to switch from chasing a spot while building to purely building, including moving a small number of vets (2-3) who could have helped chase that spot.
It's time.
