It absolutely is a strategy to be good and just because Edmonton and Buffalo have f***ed it up doesn't mean it's not effective or that it infects your locker room or organization. Look at Chicago, look at LA, look at Pittsburgh.
You couldn't be more wrong if you want to win a Cup. Just about every winner goes through a down period where they pick high and get sufficient elite talent. Then once they have enough they ramp up and win Cups.
We are short at least one top center for the future. I'd like a second as well.
If you are insinuating "tanking" is playing to lose on purpose, that is different than liquidating non-long term assets for long term assets. The former might be destructive, the latter is smart roster management.
