"The lack of cheering by atheists for the upset victory by the Giants in the Super Bowl -- overcoming preseason odds of 25-1 against them -- begs the question: Mystery:Why Do Atheists Dislike Underdogs?"
Re. my previous comment, it was after the previous year's regular season game at Wembley Stadium (which, like the first & last year's, sold out in minutes flat) a senior NFL official told the BBC on Radio 5, that should the next few year's games here in the UK be just as popular, the NFL would see no reason why such games outside the US shouldn't be a permanent part of the regular season.
Indeed, he even went as far as to say that he'd see no reason why a future Superbowl shouldn't be held at Wembley Stadium. So there's the NFL liking an underdog - the UK (a very secular country) & fans of American Football here. Two letters: P.R.
He even stated that with the NFL's plans to expand, with a number of new team franchises in the near future (PROTIP: Carolina Panthers, Jacksonville Jaguars), they would consider a UK-based team.
So should that come to pass - and such a British-based NFL franchise make it to a Superbowl, are you going to cheer for this non-American underdog, Andy Schaftafly...?
Enjoy your paradox.

No, what said NFL official referred to was adding more franchises; not changing or transferring existing ones (i.e. Baltimore Colts - Indianapolis Colts. Then the Baltimore Ravens; their mascot 'Poe' and their slogan 'Nevermore', as in not losing an NFL team again).
