When the Boston Bruins fired Bruce Cassidy in June of 2022, it not only sent shockwaves through the fanbase, but also the NHL. It was a firing that nobody saw coming and if they said they did and are outside of the front office, then they're lying.
The Bruins hired Jim Montgomery a few weeks later, which was an under-the-radar hiring, and it turned out to be a move that paid quick paid off quickly. The Black and Gold had a 2022-23 regular season that was the best in NHL history and will be very difficult to repeat anytime soon.
