It is a very select group that has only 6 members. Winning the Olympic Gold Medal and then the Stanley Cup in the same season. Ken Morrow (USA, New York Islanders) was the first to do it in 1980, and he was the lone member for 20 years until the 2000 Canadian Olympic team and the Detroit Red Wings added Steve Yzerman and Brendan Shanahan to the list. From there, the list doubled in 2010 as once again Canada and the Chicago Blackhawks allowed Jonathan Toews, Duncan Keith and Brent Seabrook to join the club.
Of the 25 players on the Canadian roster that completed the first half of the double, 20 will be participating in the Stanley Cup playoffs for their respective teams.
Toews and Keith have the opportunity to incredibly accomplish the feat twice, and in this case it would be a sandwich with two Stanley Cups acting as the bread with the Olympic Gold as the meat inside.
There are a number of teams that could have more than one player join the club. In fact, 11 of the 16 teams in the post-season have a member of the Canadian Olympic Gold Medal team.
Here is the group of players that could join the Big Double Club.
