Dallas or Arizona?

On the surface it would appear we should root for the Cowboys to beat Arizona, but in actuality should we cheer for Arizona so we have a chance at a number 2 seed? It's an interesting debate for sure. Yeah we want to win our division, but a 2 seed and home field until the conference championship would be really nice. Who knows we might get an upset and actually host the conference championship. Yeah, I know, getting way way ahead of myself, but it's fun to think about. What are your thoughts?
