What I mean, is why hasn't Oklahoma City or Salt Lake City, or Portland (or wherever) said "let's see if we can build and NFL Stadium."? (Not why hasn't a team relocated).
So far .... nothing. Not a peep. Not even a ridiculous, Don Bevaer-like inside job that makes the town's locals laugh. There has been, literally, nothing. And there are at least 4 NFL franchises there for the taking for 3-4 years now.
People who want to throw out the whole "the Vikings are gonna leave" logic bear some responsibility for having an explanation for this one.
If the Big Ten Network has taught us anything it is this, you only expand/relocate if you can't get a large TV Market as TV $ drives the machine. Baseball isn't nearly as driven by TV money as the NFL is. Plus they don't need to make up something so ridiculous when they already have L.A. in play.
