"...Of a Canadian team winning the Stanley Cup: 28 per cent..."

No, actually this has been shown to have no correlation to the number of Canadian teams in playoff contention, or even in the NHL (not 28%, but in the ball park)....(I think it was Nate Silver who ran the numbers, the article was in the NYT and re- printed in some Canadian papers as well)

I give the same as the 20+ years - 0%
