im guessing most leagues basis for defensive points are "pts allowed" ...which they have an increase of roughly 127 for the Saints. thats about 8.0 per game more. Yeah i dont see us allowing 1 td per game more thru 16 games.
In our leagues, the biggest producer of DST points are turnover, sacks, defensive TDs and special team TDs. In the past few years, we have been lame in turnovers, special team TDs and defensive TDs.
