In response to Klaas's comment:
On the flip side, does Keeping Championship Coach --> ?? --> Cup. In the semi-modern era, other than the greatest coach of all-time Scotty Bowman, Sather of the Oilers dynasty, and Al Arbour of the Islanders dynasty, the answer is a BIG NO!
No, but the point is shouldn't you make a move because you know what you need rather than just because you want a change? To me, getting rid of a coach who's winning but not winning the Cup every year in favour of an unknown who may not fit the personnel is flailing.
But Books , according to the laws of average (outside of a few cases that I mentioned), it behoves the Bruins to make a coaching change. I have faith that PC will figure out what kind of coach the Bruins will need in the future.
There is much to like in Julien's coaching system. My viewpoint is that Julien is most effective in a scenario where a team has no structure along with not much offensive talent, thus a defensive system will springboard such a team forward.
However, the Bruins now have many offensive players in their system, thus a new approach could be more effective. Basically you try to win games other than just with scores of 2-1.
