It appears to be the total of every point a team has scored to date, for and against. I played 61 games and scored a total of 17,930 points for an average of 293 per game.
So, i guess I understand the stat, but don't see it as very useful.
I looked at the behind. I thought it was the points behind the high scorer I was, but last week's numbers were not related to that as best I could tell. I lost a lot of ground when I was 2nd high scorer and only 14 behind weekly leader and ahead of overall leader.
