There are plenty of different strategies for preventing tanking. Getting closer to the end of the season always brings up the debates on which way is better. I will have to keep this short today but would like to continue ore on this topic later. My main point on leaving things as standings and not potential points is this:
If the integrity of the league is in so much question you do not trust league mates to set their line ups to the best of their ability, the issue is not in settings. The issue is with the people you are playing with.
I believe as long as owners are setting the line up every week with active NFL players who have been or should be seeing the field, there should not be interference. If this is not happeneing, the owners are at fault. It is that simple.
