When a sport expands from 13 weeks (12 regular season games plus one playoff game), to 23 weeks long, then of course events like this will frequently happen. What did you expect?
But for pompous high-and-mighty knee-jerks such as Florio, this is disingenous revisionist history. Nobody was advocating for the league to have championship games moved to a neutral site after one of the most famous games in NFL history, the Ice Bowl, which determined the NFL champion in a game played in Decemberof 1967.
Even if you play the game at a neutral site, who's to say there won't be a torrential downpour that day. Play indoors? That's completely antithetical for football purist snobs. Besides, it give a major competitive advantage to certain teams that are built for speed on a carpet.
You don't want the elements to be a factor? Then have a season that starts in early September and ends Thanksgiving Day weekend, similar to what high school football used to be back in the day. There's a better chance of me hitting the next powerball than that ever happening.
