Okay, "global" is a bit much, but the truth is that if you're not excited about the possibility of the NFL in Toronto, you don't understand the international nature of the city. Going to Europe first was a stupid idea that was rightfully shut down. Instead, you branch out to a cross section of European/American influence like Canada and see what flows across the pond.
I don't like the idea of losing the Buffalo Bills any more than most, but that team is on its way out of that city, and it's best to keep it at least within driving distance. Meanwhile, the League has the chance to get the game successfully established across a national border.
And hey, it's Canada, so it's mostly white people, so Roger Goodell will be psyched. Just kidding. But really, what's the problem with that guy and young black guys, right?
