Rules Analysis
Best perspective: The most complete view available by a player that includes the relative positions of the disc, ground, players, and line markers involved in a play. On an unlined field, this may require sighting from one field marker to another. Best perspective always belongs to a player. However, players may rely on the following sources as a component of best perspective:
Players may review officially-designated video footage to assist in resolving a call where such footage is available. However, play may not be delayed to review video footage.
For example, live instant replay in a stadium setting may be used by players to resolve a contested foul call. Players may not, however, request that a particular play be replayed on the screen. If, after reviewing the video, players still cannot agree, they should not delay the game to rewatch the play multiple times; instead, the play should be treated as a regular contested foul.
