Rule changes for 2005
There are several rules that have changed for the 2005 season. Following are some highlights:


 * In an effort to bring spearing under control, the word "intentional" was removed from the rules.
 * A listing of examples for unsportsmanlike acts was developed in order to encourage more consistent application of the rule. Examples of such acts include, but are not limited to:
 * Imitating a slash of the throat;
 * Resembling the firing of a weapon;
 * Bowing at the waist;
 * Punching one’s own chest excessively;
 * Crossing one’s arms in front of the chest;
 * Placing one’s hand by the ear as if to indicate that the player cannot hear the spectators;
 * Diving into the end zone when unchallenged by an opponent;
 * Entering the end zone with an unnatural stride (e.g., high stepping);
 * Going significantly beyond the end line to interact with spectators;
 * Standing over a prone player in a taunting manner;
 * Attempting to make the ball spin as if it were a top;
 * Performing a choreographed act with a teammate(s) (e.g., pretending to take a photo, falling down in unison); and
 * Entering the field of play by coaches or substitutes in protest of officials' calls.
 * Additionally, the committee added language to the rule that reads: "Spontaneous celebrating with teammates on the field of play, provided it is not prolonged, taunting or intended to bring attention to the individual player, is allowed."
