Las Vegas had missed out on a title in 2020 when the team was 18-4 in the coronavirus-impacted season. The team lost to the Seattle Storm. In 2008, the team was known as the San Antonio Silver Stars, and they lost in the Finals to the Detroit Shock.

Becky Hammon, a key member of that Silver Stars team, turned around and became the head coach of the Aces this season. She picks up a ring as a head coach.

Aces team owner Mark Davis was in attendance for the game. He skipped the Las Vegas Raiders’ home opener against the Arizona Cardinals to watch his team take home the hardware.
