Halfway Rankings and NEW Offensive/Defensive Rankings

Hello again my friends, its been a long time.  Truth is, its been too long.  But don’t worry, I came back with something that I am sure you will find interesting.  As you read this you will see two charts, the traditional Derby Math Rankings thru the first 6 months of the WFTDA season and then a new chart in which I incorporate Offensive and Defensive Efficiency Rankings.

The good news is that the traditional Derby Math Rankings received a little face lift as well.  In addition to number of bouts and score from the past rankings, I have added average opponent ranking (at time of bout), average points scored, and average points allowed.  As with last year I will be following the WFTDA July-June season so all data is from bouts since July 1st, 2015 and teams will only be included in the rankings once they have played a bout during this period.

It is very interesting to see where we are at so far this year.  A couple key points with the top of the rankings, it is important to remember that Rose City has a bad loss (129-193) to London in early August and that is included in the rankings.  Also, Gotham had an incredible “Regionals” outscoring Angel City, Montreal and Queen City 1,054-133.

Other stats I found interesting and worthy of note.  Atlanta and Jacksonville currently hold the two toughest schedules so far for the 2015-16 season.  There are currently 6 teams ranked in the Top 100 that are averaging more points per bout than Gotham, but the highest ranked is Royal City at #74.  The V Town Derby Dames out of Visalia, CA  currently have the 4th best points scored average and the best points allowed average of Top 100 teams but are only ranked #88.

Now for the brand new Offensive and Defensive Efficiency Rankings.  As the world of sports gets more and more data driven I spent the last few months trying to find a new way to look at derby and provide teams with a bit of insight to themselves, and their opponents.  Taking a bit of inspiration from MLB and Sabermetrics I developed methods for determining a teams Offensive and Defensive Efficiency based on the points scored, points allowed, and opponents strength.

This really provides a bit further analysis to what a teams potential strengths and weaknesses are.  It also goes deeper than just looking at points, by taking into account the opponents strength I can tell you that if you score 100 points vs Texas your Offensive Efficiency will rank you higher than scoring 100 vs Santa Cruz.  What I really hope is that this will provide people with a different perspective on just how good a team is and allow for us to look for bout match-ups with a different eye.

Just some quick observations before you read thru the rankings.  Of the top 20 teams, Atlanta has by far the biggest spread between their Offensive and Defensive ranks.  Defensively they are much further along than their offense at this point and I would normally chalk that up to their opponents (Texas, Tampa, London, and Denver) but all of their opponents have higher or equal Offensive ranks than Defensive.  As I look all the way down at #55 I come across Ft. Myers who has used two very good wins against Gold Coast to really propel their Defensive rank all the way to #16.  With all data based rankings you will almost always find someone that is a little out of place, and with limited data sets (only 2 bouts so far for them) it is not that surprising.  Their 362-25 win in August will help them a lot, but I do not expect their future bout to allow them to sustain that rank.
