The Phoenix Mercury 2023 relied on Diana Taurasi and Brittney Griner as their primary scoring options, with Griner providing interior efficiency and rim protection after returning to the lineup. Sophie Cunningham added perimeter shooting, while Moriah Jefferson handled much of the playmaking. Despite experienced contributors, the Mercury struggled on both ends of the floor, combining one of the league’s least efficient offenses with its weakest defensive performance.
