I need help with this NFL Commercial

Can someone explain to me why I should give a flying damn about this woman and her Vikings Steelers Giants Whoever family?

I mean, how could this possibly have any impact on me at all?  I'm a Patriots fan who used to be married to a Buffalo Bills fan (I lived in the Buffalo area during the four years in which that team perfected the art of losing the Superbowl, failing by a larger margin each time.)  I rooted for the Bills (the Pats stank at the time) but never became a fan.  My wife remained a big Bills fan.  The rest of my family, and hers?  Couldn't care less.  Because jeeesh- it's football, not a freaking religion.

And it's not like a Red Sox fan marrying a Yankee fan- I mean, that would be too much, of course.

So can someone explain this to me?  Please?
