Why in the hell is Minnesota choosing to go with a roofed stadium, again? It's not a coincidence they went to 4 Super Bowls playing outdoors. By default, it's one of the best home field advantages in the game, if outdoors?
Obviously winning is secondary to comfort. And, hosting Super Bowls second to actually participating in them.
