Quinn will be replacing former coach Todd Reirden, who would oversee the Penguins powerplay and defenseman. Reirden was relieved of his duties on May 3rd after a horrendous season for the Pens PP unit.
Sullivan and Quinn have ties together as friends and as teammates at Boston University from 1986-1988 and played a couple of times against each other as coaches for their respective teams when Quinn was head coach of the NY Rangers from 2018-2021. Both played, and learned, under the legendary Jack Parker at Boston University.
