Angel Reese is the 2026 Defensive Player of the Year, but what about her offense? I did a statistical deep dive, focusing some of the less measured aspects of her offense: A Statistical Deep Dive on Angel Reese’s Offense iancswan.substack.com/p/a-statisti...

Angel Reese has officially won the Defensive Player of the Year award! Last week, I wrote an article analyzing DPOY candidates, and she was my pick for the most valuable defensive player this season. Much deserved!

In game 2, the Fever made some interesting adjustments to the issues I noticed in game 1: They played much fewer minutes with Timpson and Billings because their lack of shooting gave A’ja Wilson a player to help off of, instead opting for two extra guards.

In the second half of the 2026 WNBA season, #AtlantaDream forward Angel Reese has significantly improved her scoring game. Below are aggregated shot charts before and after July 13th, showing a clear efficiency increase around the rim:

Jackie Young's aggregated shot chart for this WNBA season. It appears that she's been extremely efficient shooting from the center of the court, while less efficiently at a lower volume from closer to either sideline.

Malonga went nuts in that 4th even with such a deficit she’s gonna be amazing

Looking at my shot chart tool, the #MinnesotaLynx (left) have a very similar shot diet to the league average (right). However, they're is significantly more efficient from 3-pt range and in the short midrange/post areas, leading them to the league's #2 offense.

Marina Mabrey has been irreplaceable for the Toronto Tempo this year. The Tempo have been significantly more efficient in every 3-point region but the corners, and at the rim with Mabrey (left) than without her (right).

A'ja Wilson's 2026 shots aggregated by region with a tool I made. The MVP is extremely efficient in the restricted area, and her ~50% shooting from nearly every midrange area makes her one of the WNBA's most unstoppable scorers ever.
