The Houston Oilers were playing a AFC Wildcard game on the road in 1978, because they finished second only to the Pittsburgh Steelers that year. But not because the Miami Dolphins were a better team. Because if anything the Oilers were better, but back then and until 1990, you had to win your division in order to host an NFL playoff game. As it should be, at least as far as I’m concern. So because the Oilers were in the same division as the Steelers in 78 and finished behind the Steelers that season, the Dolphins won the AFC East, so the Dolphins hosted this wildcard against the Oilers. But the Oilers were the second best team in the AFC in 78. They just didn’t win their division, because again they were in the same division with the Steelers, the best team in the AFC in 78 and Super Bowl champion.
