Remember that scene in Pirates of the Caribbean where the ship is being sucked into the giant whirlpool and Jack Sparrow looks at his compass and it's just spinning wildly? Sometimes I think that's what's happening to Alain Vigneault when he goes into his office after losses since December.
On the bench he's lost his calm demeanor, often getting snippy with officials and no longer sporting that poker face we've seen the past two and a half years.
In that same vein, the old Vigneault is sort of leaving by the day. Vigneault is changing, and not the type of changing a coach does when things aren't working and he's adjusting his systems; Vigneault is changing the way he's acting.
