On the Sportsnet site in the NFL forum part, a discussion was centred around why the NFL doesn't ever play the Super Bowl outdoors in a northern city. After some discussion, I thought this poster summed it up well which also told me another reason why our Grey Cup is so great, not nearly as corporate and strictly money driven as the Super Bowl, the game actually counts more:
"The super bowl has nothing to do with the game it's self, or the fans of the game. It's all about giving out perks to people the NFL wants money from. Something like 80% of the seats in the building are given away by the NFL to corprate sponsers. Rich CEO types don't like sitting in the cold and snow, so it seems unlikely that the NFL will hold the game in an outdoor building."
