Looking At The Adjusted Conference Standings

In the table below, teams are ordered by their expected conference records, which are derived from each team's offensive and defensive efficiency in conference play. Expected W-L records are calculated using the pythagorean theorem, and you can read all about it here.

EFF Margin = OFF EFF - DEF EFF
ExpW-L = Expected Win-Loss Record
ActW-L = Actual Win-Loss Record
