By the way, is Jordan Greenway really the very first black U.S. Olympic ice hockey player?
Gosh, I didn't know that this sport was that white...
Well, the sport isn't nearly as white itself, as much as it is in America. Canada has a strong tradition growing every year of hockey players of color. Not too many years ago Mike Grier retired from the Buffalo Sabres. His contribution to history? He was the first African American NHL player who advanced up through the American minor leagues and development leagues. This is compared to other African Americans who moved to Canada in their teens to play and came back to America when they hit Pro.
Anywho, there are a large number of black Canadians in the sport. Several years ago the now-defunct Atlanta Thrashers had the first ever all non-white starting lineup!
but yes, in America hockey is only slowly changing its Lily white complexion, though gains are being made.
