OFFENSIVE/DEFENSIVE RATINGS

Phoenix       111.3     Indiana        96.9

New York      105.6     Seattle        98.1

Tulsa          95.4     Phoenix       111.0

The league made an enormous jump in Offensive Rating after cracking 100 for the first time (100.4) a year ago. The biggest improvement was in terms of two-point percentage, which went up from 45.5 percent to 47.2 percent. The league-wide pace was also somewhat faster, so WNBA teams averaged 80.3 points per game this season, an increase of a full two points over last year’s 78.3 ppg mark. For comparison’s sake, NBA teams average 83.7 points scaled to 40 minutes.

Individually, the big surprise was San Antonio’s late climb up the offensive leaderboard. The Silver Stars, once a defense-first outfit, now win almost exclusively on the strength of their Becky Hammon-helmed offense. The New York Liberty did make up some ground on the leaders to finish a very solid third in the league in Offensive Rating.

With Indiana finishing fourth in Offensive Rating, it’s time to shift the label of defensive specialists to the Washington Mystics, who won the Eastern Conference regular-season crown despite finishing eighth in the league in offense. The Mystics were second in Defensive Rating, just ahead of the Storm.

The weird season-long trend was that the league was top-heavy on offense and bottom-heavy on defense, where Tulsa and Phoenix were significantly worse than anyone else in the WNBA on a per-possession basis.

EXPECTED WINS STANDINGS

Team        Exp. W%     Team        Exp. W%
-------------------     -------------------
Seattle        .761     Indiana        .638
Phoenix        .504     Washington     .620
San Antonio    .393     New York       .607
Los Angeles    .391     Atlanta        .575
Minnesota      .388     Connecticut    .538
Tulsa          .112     Chicago        .476

In the end, there weren’t many notable departures between point differential and won-loss records. The most interesting was Indiana dropping to third in the East despite the conference’s best expected winning percentage. Then again, the Fever could have tied for first with a win on Sunday in a game that proved meaningless because of outcomes earlier in the day. Indiana isn’t exactly flying under the radar, though I am of the opinion that whoever wins the series between the Fever and the Liberty has a good shot at knocking off the Mystics in the Eastern Conference Finals.

In the West, the teams battling for the last two playoff spots were as close in point differential as they were in the standings. They did finish in the exact order expected winning percentage projected.

PACE RANKINGS

Team          Pace
------------------
Atlanta       82.8
Phoenix       82.6
Tulsa         81.2
Minnesota     78.5
Connecticut   77.5
League        77.2
Los Angeles   76.5
Indiana       75.3
Washington    74.5
San Antonio   74.5
New York      74.3
Chicago       74.2
Seattle       74.2

The Dream surpassed the Mercury as the league’s fastest team this year after a close competition in 2009. For the third time in as many years under Brian Agler, the Storm was last in the league in pace of play.

Had Lauren Jackson played normal minutes down the stretch, we would have had an interesting battle for the league’s best WARP rating. As it is, Jackson finishes second in the league, with Tamika Catchings No. 1 for the second consecutive season. Jackson was ahead of Catchings in terms of net plus-minus, finishing fourth in the league in the category as tracked by the Lynx’s Paul Swanson. Sylvia Fowles was part of the “big three” all season long, and I hope she isn’t passed over for All-WNBA First Team honors because her team fell out of contention. Fowles did everything she could to help Chicago.

Surprisingly, Kennewick’s own Leilani Mitchell finished a hair outside the league’s top 10 in WARP. Mitchell surely owes some of her outstanding stat line to playing alongside Cappie Pondexter, but Mitchell was outstanding in her own right, knocking down 48.6 percent of her three-point attempts, dishing assists and putting pressure on opposing point guards. I’m not sure I’m quite ready to say Mitchell is better than Liberty predecessor Hammon, but I’ll heartily endorse Mini Mi as the WNBA’s Most Improved Player. New York joined the Storm and Phoenix as teams with three players in the WARP top 20, while Minnesota (best: Lindsay Whalen, 2.9) and Tulsa (Amber Holt, 1.3) did not have any representatives in the top 20.

Charles, naturally, was the leader in rookie WARP. Epiphanny Prince (3.2 WARP, much improved in the second half) was the only other rookie of note. Prince gave DeWanna Bonner (3.3) a good run for top reserve WARP as well. Look for big things from Prince next year if she steps into Chicago’s starting lineup.

Camille Little sea .577 3.1
