Following an illustrious 13-year stint in the Bay Area, Klay Thompson is set to embark on a new chapter with the Dallas Mavericks, complete with a new jersey number.
The veteran Warriors star signed a three-year, $50 million deal with the Mavericks in a sign-and-trade agreement, marking the end of an era with Golden State.
During his time with the Warriors, Thompson was a dominant force, earning five All-Star selections, two All-NBA nods, and four NBA championship rings.
Despite his success in No. 11 with the Warriors, Thompson will don a different number in Dallas due to Kyrie Irving already holding the No. 11 jersey.
Why is Klay Thompson switching jersey numbers?
Thompson will wear No. 31 with the Mavericks, a number he chose in honor of Jason Terry, who won a championship with the Mavericks while wearing that number.
Thompson also mentioned his desire to surpass Reggie Miller on the all-time 3-point list while wearing No. 31 as a tribute to the former player.
Throughout his career, Thompson has worn No. 1 during his high school and college days, earning accolades and having his jersey retired at Washington State.
