Could be. The way the Bruins played the first three games of the series you knew they were on a mission. The likelihood of the Rangers coming out on top was slim. Maybe ole Slats decided to make the decision to keep his own head out of the public noose. We all know he's pretty much hired for life....but when the public goes bonkers, especially nowadays with the huge roar we can all make through social media....sometimes people are forced to listen.
Much easier to shove the grumpy, media hatin' old coach under the bus. Force him to make a personnel decision he hates, and the casual fans will (and did) scream over, to make Torts the perfect sacrificial lamb. No one would question why or how, just get the nasty bum outta here!
This move easily buys Slats a few more years, cause, ya know, it takes a few seasons to fully implement a new system, get it working down on the far as well, bring in a new crop of prospects in a new direction, etc, etc....
