Ranking All 31 NFL Stadiums For 2015 - From Worst To Best

6. University Of Phoenix Stadium - Arizona Cardinals

The University Of Phoenix Stadium looked magnificent during the latest Super Bowl, as if a UFO had came down to Earth, nestled itself in the desert, and opened up to put on a fantastic show. Not only does the stadium look modern and insane from the outside, but its a mighty impressive building inside, with the much-publicised pitch able to slide through a slot in the bottom of the stand and soak up the Arizona sunlight, before seamlessly gliding back into position.
