Super Bowl curse

The home field curse affects the host team of the Super Bowl. So far no team has yet managed to reach the Super Bowl in their home stadium. Four teams with Super Bowls in their home venue have qualified for the divisional playoffs: the 1994 Miami Dolphins, the 1998 Miami Dolphins, the 2016 Houston Texans, and the 2017 Minnesota Vikings, the Vikings being the first to qualify for their conference's title game. From 1966--2011 (excluding the six Super Bowl games held in a stadium without a professional team), the Super Bowl host team has had 11 winning seasons, four split seasons, and 25 losing seasons. Mathematically, the probability of that many losing seasons or more occurring by chance (assuming a 50 percent chance of having a losing season (disregarding .500 seasons)) is 7.69 percent. It should be noted, however, that the Super Bowl host stadium is selected several years before the game is played, without regard to the teams that qualify.
