"I am happy for Billy, and going to miss having him around," Crosby said. "He's always been respected on and off the ice. He is a great leader and was always there for me since the day he came to Pittsburgh. I know he'll be a great general manager."
Pittsburgh made such an impact on Guerin that following his retirement, he did so as a Penguin and made his post-career home in the city.
"We were only here a short time, but my family and I developed such a deep connection to the city, the team and the fans," Guerin said at his retirement. "It was amazing. From ownership to the front office to the coaching staff to trainers, from my teammates to the arena workers to the people in the stands, they all treated us in such a first-class manner. We all agree that retiring as a Pittsburgh Penguin is the perfect thing to do."
A year later, the team hired him as a development coach and promoted him to general manager three years later.
In both roles with the team, Guerin was crucial in the maturation of the team's prospects. It was many of those prospects - such as Matt Murray, Brian Dumoulin, Jake Guentzel, Bryan Rust, Tom Kuhnhackl and Conor Sheary - that would help the club win back-to-back titles.
"Billy's insights and knowledge of the game were helpful to myself and the coaching staff," said head coach Mike Sullivan. "We're grateful for all he has done for us. I'm personally excited for his new endeavor and wish him much success."
Guerin played 18 NHL seasons and was a member of the 400-400 club with 429 goals and 427 assists for 856 points. He won two Stanley Cups (New Jersey, 1995; Pittsburgh, 2009). He played his final 95 games in the league as a Penguin.
In the 2009 Stanley Cup run, Guerin played wing with Crosby and notched seven goals and 15 points in 24 games. The Wilbraham, MA native is a member of the United States Hockey Hall of Fame and participated in three Olympics (1998, '02, '06), earning a silver medal at the 2002 Games.
