 Clay Thompson says he remembers telling Luka Doncic he thought the Dallas superstar was on a path to greatness after Golden State beat the Mavericks in the Western Conference Finals two years ago. Now that Thompson has left the only NBA team he's known in 13 years to join Doncic and Kyrie Irving in Texas, he's ready to celebrate with rather than console the 25-year-old sensation. Thompson joined the Mavs in a sign-and-trade deal involving six teams and a $50 million three-year contract for the 34-year-old, a five-time All-Star.
