Scoring is a difficult thing to determine for a fantasy sports league. Therefore, we have decided to let the teams decide themselves the scoring for our fantasy scores. The teams in the fantasy league consist of an offense and a defense for scoring. The results of the actual games determines how many points are awarded based on the tables to the left. If the offense scores more, then add the following based on the difference.
Differential Scoring will be a key component to the scoring formula. It allows for teams to get extra points when their offense scores more than their defense gives up. But it also allows teams to lose points if their defense gives up more than their offense scores. The differential could account for up to a 40 point swing in games, which means that everyone should be in every game just like in the real league. - Michael Scaggs, writer League Scoring Rules for Arena Football
