The first Eagle to win the Stanley Cup as a player was Joe Mullen in 1989 with the Calgary Flames. Mullen would also win the trophy in 1991 and 1992 with Pittsburgh. BC hockey alumnus Kevin Stevens also played for the 1991 and 1992 Pittsburgh Penguins.
In 1994, Brian Leetch won the Stanley Cup with the New York Rangers. The next year, Bill Guerin won the Cup with the New Jersey Devils. To round out the '90s, Doug Brown won Stanley Cups with Detroit in 1997 and 1998.
Brian Gionta was the first former Eagle to win a Stanley Cup in the new millennium when the Devils won it all in 2003. An Eagle didn't win again until 2007, when Ryan Shannon and the Anaheim Ducks took home the Cup.
Three Eagles were on Pittsburgh's 2009 Stanley Cup winning team: Brooks Orpik, Bill Guerin, and Rob Scuderi. Scuderi went on to win the 2012 Stanley Cup with the LA Kings.
The last Eagle to win the Stanley Cup before Dumoulin did it this year was Ben Smith, who played one playoff game with the 2013 Chicago Blackhawks.
For comparisons sake, former BU Terriers have won the Stanley Cup 9 times. BC is second only to Wisconsin, whose players have had their names etched on the Cup 18 times. Michigan and North Dakota come closest to BC, with players winning the Stanley Cup 15 times each.
