 A lot of money in the NBA is what I'm seeing. Free agent guard Clay Thompson signs a three-year deal with the Dallas Mavericks. 13 years with Golden State, four championships with the Warriors. This required a sign-in trade that involved the Hornets, who received forward Josh Green from Dallas as part of this deal and sent two second-round picks to the Warriors. Green averaging eight points per game last season for the Mavericks. Boston Celtics star Jason Tatum, the largest deal in NBA history, $314 million on a five-year contract extension.
