This set of stats includes a Homemade Sagarin. Baltimore seems atop most metrics today, though Green Bay has a better record, and also a better SRS. Teams that have played better than their record include Arizona, Philadelphia, and Minnesota.
Median is the median point spread. HS is the homemade Sagarin, Pred is the predicted pythagorean expectation. SRS, MOV, and SOS are the simple ranking components (simple ranking, margin of victory, and strength of schedule respectively).
