Advanced Stats: Picking All-Star Reserves

Posted on Monday, July 18th, 2011 at 6:25 pm by Kevin Pelton

We’re a week away from the All-Star break and as of today more than 40 percent of the WNBA’s regular-season schedule is complete, believe it or not. Here’s the latest advanced statistical breakdown of the league. As always, see our updated Statistical Analysis 101 page for explanations of these stats.

OFFENSIVE/DEFENSIVE RATINGS

Team           ORtg     Team           DRtg
-------------------     -------------------
Phoenix       111.8     Minnesota      94.7
San Antonio   106.4     Chicago        96.9
New York      106.1     Seattle        97.0
Los Angeles   105.9     New York       99.7
Minnesota     105.8     Indiana       100.0
Indiana       105.5     San Antonio   100.3
Connecticut   102.6     LEAGUE        101.6
LEAGUE        101.6     Atlanta       101.7
Washington     98.3     Connecticut   101.9
Chicago        98.0     Phoenix       103.4
Seattle        96.5     Los Angeles   106.4
Atlanta        93.5     Washington    107.3
Tulsa          89.6     Tulsa         110.0

Suddenly, the Mercury offense has become significantly more efficient than any other in the league. The style Phoenix playing right now – dominant offense and decent defense – has been a highly successful one for the Mercury in the past. On defense, the big mover last week was the Liberty, which vaulted from eighth to fourth. Playing the league’s two worst offenses will help that process, but New York also did a good job defensively against the Connecticut Sun in a game lost by uncharacteristically poor offense.

EXPECTED WINS STANDINGS

Team        Exp. W%     Team        Exp. W%
-------------------     -------------------
Minnesota      .753     Indiana        .610
Phoenix        .735     New York       .586
San Antonio    .687     Connecticut    .558
Seattle        .525     Chicago        .498
Los Angeles    .459     Atlanta        .345
Tulsa          .000     Washington     .292

With the Fever slumping a bit, the East has gotten much tighter at the top. Chicago still has the opportunity to make it a four-team race. In the West, Phoenix has leapfrogged San Antonio in terms of point differential. The Tulsa Shock has struggled so badly recently that a team with the Shock’s point differential would not be expected to win all season. Obviously that’s preposterous, and differential isn’t meant to be taken so literally at the extremes, but there is a lot of room for improvement in Tulsa’s current form.

WARP LEADERS

Player               Tm   Win%   WARP
-------------------------------------
Sue Bird            SEA   .639    2.2
Diana Taurasi       PHO   .628    1.9
Swin Cash           SEA   .607    1.9
Maya Moore          MIN   .608    1.6
Candace Parker      LAS   .728    1.5

Cappie Pondexter    NYL   .659    2.6
Katie Douglas       IND   .697    2.5
Tamika Catchings    IND   .736    3.3
Angel McCoughtry    ATL   .526    0.8
Tina Charles        CON   .606    1.8

We’ll look first at the starting lineups for Saturday’s All-Star Game. In the West, despite being injured, Candace Parker is still the most valuable center, so it’s hard to be too critical of fans voting her into the game. Personally, I think there’s fan voting for a reason, so I wouldn’t complain anyways. The healthy selection who’s drawn the most ire is rookie Maya Moore, who led all players in balloting. Moore has, statistically, been better than you’d believe from that reaction. She’s a versatile contributor and rarely turns the ball over. Teammate Rebekkah Brunson has been better, certainly (to say nothing of Penny Taylor) but Moore would belong in contention for a spot as a reserve.

In the East, I’d have gone Sylvia Fowles over Tina Charles, but again Charles belongs on the team. Angel McCoughtry’s low WARP total stands out. However, the alternatives at forward in the East were also relatively week.

Player               Tm   Win%   WARP
-------------------------------------
Penny Taylor        PHO   .743    2.9
Candice Dupree      PHO   .621    1.9
Rebekkah Brunson    MIN   .640    1.9
Danielle Adams      SAS   .737    1.9
Lindsay Whalen      MIN   .639    1.8
Becky Hammon        SAS   .638    1.8
Kristi Toliver      LAS   .639    1.6
DeWanna Bonner      PHO   .621    1.4
Sophia Young        SAS   .583    1.3
Jia Perkins         SAS   .592    1.2

Now let’s take a look at the reserves and fill out a ballot. (Like Storm Head  Coach Brian Agler, I’ll vote strictly for players from the other West teams.) At guard, Becky Hammon and Lindsay Whalen are easy choices. At forward, I’ll go for the Mercury’s duo of Taylor and Candice Dupree. That leaves the matter of center, where the best player in terms of WARP has been Phoenix’s Kara Braxton (1.1). I’d argue Brunson, who occasionally plays the pivot, ought to be eligible. If the picks are made strictly by positions on the ballot, then I’m going to use the loophole to pick rookie Danielle Adams, who wasn’t on the ballot as a reserve, and make Brunson a utility pick.

Strictly by the numbers, Kristi Toliver would be the president’s choice to replace the injured Parker on the roster, but I’d probably lean toward giving the hometown crowd another representative and choosing Sophia Young.

Player               Tm   Win%   WARP
-------------------------------------
Sylvia Fowles       CHI   .715    3.3
Epiphanny Prince    CHI   .635    2.4
Renee Montgomery    CON   .634    1.9
Jessica Davenport   IND   .628    1.6
Essence Carson      NYL   .658    1.6
Kia Vaughn          NYL   .535    1.3
Kara Lawson         CON   .562    1.1
Nicole Powell       NYL   .537    1.1
Plenette Pierson    NYL   .528    1.0
Nicky Anosike       WAS   .515    0.9

In the East, if Fowles isn’t the backup center, we should call off the whole competition. Fortunately, I think we’ll be OK there. At guard, it’s the young duo of Renee Montgomery and Epiphanny Prince that has claimed places on the roster. The utility spot goes to Indiana’s Jessica Davenport, in the midst of a breakout season. Forward is a little trickier. If I could stretch positions, I’d pick Essence Carson, the best of a bunch of Liberty options near the middle of the East pack. Otherwise, Nicole Powell or Plenette Pierson is an acceptable pick. For the last spot, I’m going slightly off the board to take Crystal Langhorne. Langhorne’s just outside the top 10 East non-starters in WARP in part due to injury, and she has a better track record of success.
