Klay Thompson has left the Golden State Warriors to join the Dallas Mavericks on a three-year, $50 million sign-and-trade deal. Despite his storied 13-year tenure and four championships with the Warriors, the team planned to bring Thompson off the bench behind sophomore guard Brandin Podziemski, prompting his departure. The Mavericks, coming off an NBA Finals loss to the Boston Celtics, hope Thompson's 3-point shooting will complement their star backcourt of Luka Doncic and Kyrie Irving. The trade also involves sending Josh Green to the Charlotte Hornets. Thompson turned down offers from the Warriors and the Los Angeles Lakers, opting for Dallas where he sees better championship prospects. This move signifies the end of the 'Splash Brothers' era and raises questions about the Warriors' future competitiveness.
