What number will Klay Thompson wear with Mavericks? Why No. 11 won't be available to sharpshooter in Dallas

After a legendary 13-year run in the Bay Area, Klay Thompson will have to get used to some new digs — and a new jersey number.

The longtime Warriors wing inked a three-year, $50 million contract with the Mavericks via a sign-and-trade deal, ESPN's Adrian Wojnarowski reported Monday. The move brought a sudden end to one of the most successful tenures with a single franchise in league history.

Over the course of his glittering spell with Golden State, Thompson was a force. He compiled five All-Star appearances, two All-NBA selections and, most notably, four championship rings.

Thompson did all of that while sporting a familiar digit on his back: No. 11, an integer that been significant all throughout his life. But he won't be doing so in Dallas. Here's why.

Why can't Klay Thompson wear No. 11 with the Mavericks?

The reason why Thompson, 34, won't be wearing No. 11 is a simple one: It belongs to someone else.

Mavericks guard Kyrie Irving received the number after his arrival in Dallas during the 2022-23 season.

Irving, an eight-time All-Star, three-time All-NBA selection and fellow NBA champion, has quite an impressive resume himself. Thompson isn't enough of a star to displace Irving as holder of No. 11. The Washington State product will have to settle for another digit instead.

What number will Klay Thompson wear with the Mavericks?

Thompson and his new organization have yet to decide what number he'll wear in his new home. There is one number that he could feel compelled to cloak himself in, however.

During his high school and college days, Thompson wore No. 1 to great acclaim. Thompson's college career was sparkling, with the former Cougar twice earning All-Pac-12 honors for his exploits. He was eventually inducted into Washington State's Hall of Fame, having his jersey number retired in the process.

Similar showcases with the Mavs would represent a good return for Dallas' investment.
