Speaking of Championship pedigrees in head coaching candidates - Mike Vellucci.
For those who do highly value Championships in their coaching search (and it's certainly not an end-all be-all when evaluating candidates, there are plenty of other factors to consider), it's hard to do better than Vellucci has done. He's won at every level he's been a head coach.
Vellucci has 2x NAHL Championships (98, 99), 1x OHL Championship (2007), and 1x AHL Championship (2019). He also now has NHL experience, spending the last three seasons as an assistant coach for the Penguins. Conversely, if there's a demerit on his resume, it could be the Penguins relative lack of success since his arrival in Pittsburgh, although many might point first towards Sullivan, Hextall, or the advancing age of their stars.
