A First Look at WNBA Numbers

Posted on Tuesday, May 27th, 2008 at 5:40 pm by Kevin Pelton

Though the Storm is more than a tenth of the way through the 2008 season, it’s still very early. Nothing shows that more than the fact that 10 days into the season the Minnesota Lynx is still sitting on one game played. Still, it’s never too early to at least glance at the advanced statistics.

In terms of Offensive Rating, the surprising 3-0 Connecticut Sun laps the rest of the league.

Team       ORating------------------Connecticut  114.8Los Angeles  109.4Minnesota    106.6Phoenix      102.1San Antonio  101.1Chicago      100.3Detroit       99.0Seattle       98.8AVERAGE       96.5Sacramento    90.6New York      90.2Indiana       89.7Houston       85.2Atlanta       84.0Washington    83.8

Talk about a disparity between the haves and the have-nots – look at that gap between the Storm and the Monarchs, bridged only by league average. That San Antonio’s offense has played so well early despite some subpar shooting from Becky Hammon and two games without Ann Wauters should make the rest of the WNBA afraid. Very afraid.

Team       DRating------------------Indiana       83.8Connecticut   84.9Minnesota     86.7Los Angeles   90.5Detroit       91.3New York      93.7Chicago       94.3Washington    95.0San Antonio   95.9AVERAGE       96.5Seattle       98.2Houston      100.9Sacramento   102.9Phoenix      107.0Atlanta      114.3

Definitely a skewed distribution in terms of Defensive Rating; nine of the 14 teams in the league are above-average, in no small part because the Dream’s defense has been a nightmare. (Sorry, bad pun.) Phoenix’s defense also has to be a major concern – weren’t the Mercury supposed to be better at that end with traditional post players? Don’t look for Connecticut and Minnesota to maintain their lofty defensive perches, but the Fever might easily lead the league in Defensive Rating wire to wire.

Too early for Pythagorean records, at least as long as the Sun is projected to win more than 34 games and Atlanta to lose more than 34. Moving ahead, here are your early leaders in PER, including some surprising names.

Player              Tm   PER----------------------------Charde Houston     MIN  43.1Sidney Spencer     LAS  37.7Katie Douglas      IND  34.7Sophia Young       SAS  34.4Lisa Leslie        LAS  33.9Candace Parker     LAS  32.9Lindsay Whalen     CON  31.2Nicky Anosike      MIN  30.9Candice Dupree     CHI  30.2Plenette Pierson   DET  29.2

I don’t count on Houston, Spencer and Anosike staying up there with more minutes, but Pierson’s fast start might not be a fluke. Bill Laimbeer ought to get her more time so the Shock gets off to better starts.

    Hey Kevin,

    I’m not much of a stats geek, but one of the stats you show sometimes is “expected wins”. Can you explain that one for us.

    Thanks

  2. Kevin Pelton says:

    Sure. I use the terms “Expected Wins” and “Pythagorean Wins” synonymously. The general theory is that there’s a consistent relationship between a team’s point differential and its record. Because differential isn’t as highly influenced by the outcome of close games, it tends to be a better indicator of a team’s underlying ability, which is why it’s useful to look at Expected Wins.

    Specifically, historically each point of differential is worth a little over one win over the course of the WNBA season. You can use that relationship to calculate Expected Wins.

    I’ll probably get them in next week when everybody’s had at least a few games.

    Kevin, thanks for providing those numbers. The numbers tell us a lot about what’s going on in the lead, and confirm the Dream’s defensive woes.
