With not making the Sparks roster, Billings was signed by the Dallas Wings to a hardship contract following their season opening, as Natasha Howard sustained an injury.[6] Billings quickly was inserted into the Wings's starting lineup and became a force. In her second game with Dallas, against the Atlanta Dream on May 21, she scored 20 points and 10 rebounds.[7] Natasha Howard returned from injury, but the Wings were dealt more injuries to Maddy Siegrist, Jaelyn Brown, and Satou Sabally, which allowed Billings to continue to stay in Dallas. Following the Olympic break, the Wings's players became healthy, which forced the Wings to have to release Billings from her hardship contract.[8]
