If you want proof that no NHL coach has job security, look at what's happened over the last week.  Boston is off to a slow start but after setting records two seasons ago and winning a playoff series six months ago, nobody saw him getting fired before American Thanksgiving.  However, the news broke early on Tuesday that Boston was moving on with Joe Sacco as the interim coach.  Then, on Sunday, St. Louis made a quick move to hire Montgomery.  You have to feel bad for Drew Bannister, who only coached 76 games with the Blues and was a shocking 39-31-6 despite a weak roster, even though he was only 9-12-1 this season.
