Plum has also been named one of the five finalists for the Wooden Award, an award handed out to the best player in women’s college basketball, in the eyes of 250 sportscasters and writers. Plum was also named the AP player of the year for women’s college basketball, the first ever Washington Husky to earn the award. Other accolades Plum accumulated during her senior year include being a part of the all-Pac-12 team as well as winning the Pac-12 player of the year award, only the second husky ever to win the award, according to The Seattle Times’ website. Plum also earned the Nancy Lieberman award, an honor given to the top point guard in women's college basketball, as well as the Dawn Staley award, handed out to the best guard in women's college basketball. Plum ended her outstanding career with a point total of 3,527 and an assist total of 519. She finished just 270 points shy of Pete Maravich's all-time scoring record regardless of gender. Plum graduated from Washington in June 2017 with a bachelor's degree in anthropology. Plum was selected as the first pick of the 2017 WNBA draft by the San Antonio Stars. This marked the first time in history that the first overall pick from the NBA (Markelle Fultz) and the WNBA came from the same school (University of Washington) in the same year. Plum made her career debut on May 25, 2017, against the Dallas Wings, she scored four points along with one assist off the bench in a 94–82 loss. On August 5, 2017, Plum scored a career-high 23 points in an 87–80 overtime win against the Seattle Storm. By the end of the season, Plum averaged 8.5 ppg and was voted on the All-Rookie Team, but the Stars finished with the second worst record in the league. In 2018, the San Antonio Stars would relocate to Las Vegas, Nevada and would be renamed the Las Vegas Aces. In the 2018 season, Plum would improve in every statistical category, averaging more points, rebounds and assists with higher shooting percentages. This helped the Aces improve overall from last season but fell short of playoff spot as they finished 9th place with a 14-20 record (6 wins better than last season). In 2019, the Aces would finish the season as the number 4 seed with a 21-13 record, making the playoffs for the first time since 2014. They would receive a bye to the second round.
