The season ended with Super Bowl XIX when the San Francisco 49ers defeated the Miami Dolphins. This was the first Super Bowl televised by ABC, who entered into the annual championship game rotation with CBS and NBC. This game marked the second shortest distance between the Super Bowl host city (Palo Alto, CA) and a Super Bowl team (San Francisco 49ers). The first was The Los Angeles Rams, who's home was The Los Angeles Memorial Coliseum before moving to Anaheim the year after playing in Super Bowl XIV vs The Pittsburgh Steelers, at the Rose Bowl in Pasadena, Ca.
The 49ers became the first team in NFL history to win 15 games in a regular season and to win 18 in an entire season (counting post-season).
The penalty for a kickoff or onside kick that goes out of bounds is 5 yards from the previous spot and a re-kick must be made. However, if the second (or more) kickoff or onside kick goes out of bounds, the receiving team may choose instead to take possession of the ball at the out of bounds spot.
Leaping to try to block a field goal or an extra point is illegal unless the defensive player was lined up at the line of scimmage.
A kicker or holder who fakes being roughed or run into by a defensive player can receive an unsportsmanlike conduct penalty.
Unsportsmanlike conduct will also by called for any prolonged, excessive, or premeditated celebration by individual players or a group of players. This is usually referred to as the "Mark Gastineau Rule" because a major reason why this change was made was to stop him from performing his signature "Sack Dance" every time after he sacked an opposing quarterback.
