In your non keeper leagues, do you shuffle divisions each year? The theory that is being discussed in our redraft league is that we have some owners who are generally weaker when it comes to football knowledge and don't build very good teams and therefore do not do very well. They tend to be easy wins and if you are in their division, you play them twice and increase your win %. Shuffling divisions would also change schedules year after year which is also a positive.
