Coach Sullivan on Dumoulin: "He was such a big part of the teams that won the Stanley Cup in 2016 and 2017. He’s a great person and a great leader off the ice and in the locker room. All our players had a ton of respect for Dumo and the leadership that he brought to the team. He was a voice of reason. I can’t say enough about his contribution to making the Penguins what we are." Thank you, Brian Dumoulin.
