Mike Sullivan, who led the Pittsburgh Penguins to back-to-back Stanley Cups in 2016 and 2017, is out as the team's head coach, it was announced on Monday. Sullivan was the longest tenured coach in Pittsburgh history after just completing his 10th season.

The decision ends a fantastic run by Sullivan, who was hired by the franchise during the 2015-16 season after it fired Mike Johnston. In Sullivan's first year with the team, the Penguins won the Stanley Cup. They did it again the following year, giving Sullivan two championships in his first two seasons with the franchise.

Sullivan's final chapters in Pittsburgh weren't great, but he is a giant in Penguins history and will be remembered as such.
