Good point, but you forgot one specific small-market team.
The Green Bay Packers.
I've been to Green Bay...it's almost like a religion up there. And they are the smallest market of all...even though they draw from all over Wisconsin and the UP of Michigan, Green Bay is only about the size of Niagara Falls.
Buffalo is third-smallest, only Jacksonville and Green Bay are smaller. But, like Green Bay, Buffalo draws from a regional area; specifically Rochester, Syracuse, Erie, and the entire southern half of a province of another country. It's a bigger market than people realize.
And I agree. Go BILLS!
