Fair Play Index
The Fair Play Index is used in the Super League and Co-operative Championship rugby league competitions as a measure to determine the fairest team over the regular season. The team with the lowest points total wins. As a result of sponsorship from Frontline, the Index is currently officially known as the Frontline Fair Play Index.
