After winning two of their first three games on the road the 49ers lost their first game at Candlestick Park to the Los Angeles Rams 20-13.  The 49ers would rebound and win the NFC West for the second year in a row by posting a 9-5 record.

Earl Campbell would lead the NFL in rushing for the second consecutive year and set a franchise record for most touchdowns in a season with 19.  The Oilers would make the playoffs again as a wild card.  In the wild card game, they beat the Denver Broncos 13-7, and then defeated the San Diego Chargers 17-14 in San Diego to reach their second straight AFC Championship game.  Unfortunately for them, they had to once again run into the Pittsburgh Steelers, who a year earlier had eliminated them 34-5 in the previous AFC Championship game.  The Oilers lost the game 27-13.  The game included a controversial moment in which wide receiver Mike Renfro had a touchdown called back after the referees of the game took a long decision to decide the ruling on the field.
