You must be a big fan of domes, then.
For myself and many others, an essential element of football is that it can be all about randomness and how a team proves its superiority in the face of the unexpected and the uncontrollable. To me, at least, that's at the heart of the sport.
Think of what are commonly regarded as some of the greatest games of the last half century: the Ice Bowl 1967 (Lambeau), the Snow Bowl 2002 (Foxboro), The Greatest Game Ever Played 1958 (Yankee Stadium). They were all characterized by what you would probably describe as "random" adversity and how teams had to confront, manage and overcome it.
Think too of the great owners in the league today; they have all chosen to build outdoor stadiums in cold or challenging environments over the last decade or so: the Krafts, the Mara's, the Rooney's.
