Given their place in the standings, to my eyes it appears they are "fake good" as they really haven't proven they can beat good teams or even beat bad teams consistently.
They've beaten 2 good teams: Vegas and Minnesota. They've also lost to Vegas
They've lost to the only other good teams they've played: Vancouver, Calgary and Colorado
They've lost to bad or perceived lesser teams: Chicago, San Jose, Buffalo, Boston, Ottawa
We will see how this plays out over the next 5 games where on paper, they should probably win 4 of 5 with the biggest test coming next week vs Winnipeg.
December could be rough. 11 games including Dallas, Minnesota, New Jersey, Rangers, Washington and Edmonton.
