1988 NFL season

The 1988 NFL season was the 69th regular season of the National Football League. The Cardinals relocated from St. Louis, Missouri to the Phoenix, Arizona area becoming the Phoenix Cardinals but remained in the NFC East division.

This season marked the final coaching season for the legendary Tom Landry.

The season ended with Super Bowl XXIII when the San Francisco 49ers defeated the Cincinnati Bengals.

Major rule changes

 * A standard system of two time intervals between plays are established (and would be timed using the play clock): For normal plays, the offensive team has 45 seconds to snap the ball after the previous play is signaled dead. After time outs and other administrative stoppages, the time limit is 30 seconds beginning after the Referee signals that the ball is ready to resume play.
 * If a fumble occurs during an extra point attempt, only the fumbling player can recover and/or advance the ball. This change closes a loophole in the "Stabler Fumble Rule" that was enacted during the 1979 NFL season in reaction to the Holy Roller Game.
 * The penalty for "Running into the kicker" is changed from five yards and a first down to just 5 yards.
 * Referees were outfitted with white hats while all other officials wore black hats, which was the standard practice in college and high school football. From 1979 through 1987, referees wore black hats while all other officials wore white hats.
