The exciting part about this exercise is that we can follow the ups and downs of our beloved Saints throughout the regular season via the variations of their odds not only to make it to the Super Bowl, but first to even make it to the playoffs, win the NFC South, or earn a first round bye in the playoffs.
My favorite website to look at Super Bowl odds throughout the regular season is Five Thirty Eight (FTE). They use the well-oiled Elo rating system. The system was invented by physicist Arpad Elo, and originally designed to rate players in zero-sum games, like chess.
