The officiating position titles of back judge and field judge were swapped to become more consistent with college and high school football. The field judge is now 20 yards deep, positioned on the same sideline as the line judge, while the back judge is 25 yards from the line of scrimmage near the center of the field.
Tinted visors on players' facemasks are banned except for medical need.
A defensive player can no longer flinch before the snap in an attempt to draw movement from an offensive lineman.

During the season, the rules regarding the coin toss were changed to where the visiting team must make the call before the coin is tossed instead of while it was in the air. On Thanksgiving, the game between the Pittsburgh Steelers and Detroit Lions went to overtime. During the coin toss, Steelers running back Jerome Bettis was heard calling "tails" but referee Phil Luckett claimed he said "heads". The coin landed on tails, and the Lions won the toss and eventually the game on a Jason Hanson field goal. It was later revealed that Bettis had changed his mind during the call and was originally going to call "heads" but stopped. Thus, the rule change was adopted to prevent any further confusion.
This was the first season that CBS held the rights to televise American Football Conferencegames, taking over the package from NBC. Meanwhile, this was the first time that ESPN broadcast all of the Sunday night games throughout the season (this was also the first season in which ESPN's coverage used the Monday Night Football themes, before reverting to using an original theme in 2001). This was also the first season were the late games kickoff at 4:05pm ET & 4:15pm ET due to the 1:00pm games still going on pass 4pm to give more time for viewers to finish the 1pm games before they catch the late games before they kickoff. The 4:15pm games lasted until the 2011 season.
