Everything you need to know about Claude Julien's firing

Claude Julien used to be the NHL's longest-tenured head coach.

The 56-year-old was relieved of his duties by the Bruins on Tuesday morning, in his 10th season with the club. Julien departs Boston with an impressive 419-246-94 record - a .614 winning percentage - and a Stanley Cup ring won in 2011.

With Boston in danger of missing the playoffs for the third straight season, general manager Don Sweeney decided it's time to shake things up. Here's what you need to know about the league's latest coaching change:

Julien makes sense for Golden Knights

• Julien leaves with the Bruins ranking first in the NHL in puck possession, getting the most out of his roster after difficult - and sometimes curious -decisions that were made following the 2011 Cup win. Based on his resume, put him atop the list of candidates for the expansion opening in Las Vegas. Read more.

Odds set on Bruins' next coach
