Depends how big of a lens you view this from. They've done a decent job of it this year, but wasn't the fact they go into coast mode part of the reason Maurice walked away, and lots of those players are still there.
But even looking at this year, there's a little evidence of it, but their hot runs have extended so long that it doesn't matter. Their season to date:
Games 1-16 - 15-1 record
Games 17-43 - 13-11-3 record
Games 44-59 - 14-2 record
Games 60-69 - 5-4-1 record.
That's not to suggest those records outside the two hot streaks are terrible, but make no mistake this season is about two amazing 16 game stretches by Winnipeg and treading water outside of those.
Overall like many good teams they seem to be really be a team that builds off wins. 13-7-2 after a loss (a great record for sure) but 33-11-2 after a win (legendary).
Edmonton's does a bit similar but to a lesser extent and bit more susceptible to a losing streak. 15-12-1 after a loss, but 25-11-3 after a win.
Looking at odds in both scenarios, I'd rather face Winnipeg with them coming off a loss and Edmonton a win than any other scenario.
