The current issue of Pittsburgh magazine features an excoriating article by the excellent Sean Conboy, who shines a light on how the NFL's extortion con game worked to extreme effect in Minnesota. Highly recommended. You can read it here.
When the Steelers played in London earlier this season, lots of casual observers wondered why, so Joey Porter's Pit Bulls felt duty-bound to tell the truth about why the NFL sends teams like the Vikings and Jaguars over there every year -- it's the NFL's blatant attempt to strong-arm the people (legislators) of those locales into building a new taxpayer-funded stadiums. The NFL basically tells the fans in those cities that if their tax dollars don't get spent on new stadium deals, their teams can be moved (to London, Los Angeles, anywhere).
Oh, and by the way, the 2-5 Steelers are still the only team the 1-6 Viking have beaten this year.
