Two days after the free agency market opened, Thompson's next move was confirmed, signing and trading to the Mavericks on a three-year, $50 million contract. It was a three-way deal, with the Mavericks getting Thompson and a second-round pick from the Hornets, the Warriors getting two second-round picks from the Hornets in 2025 and the Mavericks in 2031, and the Hornets getting Josh Green.
It is worth mentioning that the Warriors had offered Thompson a two-year contract extension of around $50 million before last season, but Thompson turned it down. Later, Dream Chase signed a four-year, $100 million contract extension with the Warriors, and Thompson felt that he was not respected enough, so he made up his mind to leave the Warriors.
However, Thompson rejected the Warriors' two-year, $50 million contract, but accepted the Mavericks' three-year, $50 million contract. In addition, the Lakers also offered Thompson a four-year, $80 million contract, but Thompson also refused, and chose to join the Mavericks instead. It seems that Thompson's most important thing is not money, but whether he is respected enough and his status in the team.
After joining the Mavericks, Thompson's 13-year Warriors career officially came to an end. Thompson, the No. 11 pick in the first round in 2011, has played for the Warriors since being drafted, winning four championships, five All-Star selections, two All-Three selections, and one All-Second Defense selection during his 13-year Warriors career.
On January 24, 2015, Thompson scored 37 points in a single quarter and hit nine three-pointers in a single quarter, breaking the NBA's personal single-quarter scoring and single-quarter three-point shooting records. On October 30, 2018, Thompson hit 14 three-pointers in a single game, breaking the NBA's personal single-game three-point record. Thompson scored a total of 15,531 points in his Warriors career, ranking sixth in team history. Thompson has also hit 2,481 three-pointers in his career, sixth all-time and second all-time behind Curry.
Thompson played for his parent team for 13 seasons before leaving, which was also the seventh-longest record in history, tying Gary Payton (SuperSonics). Parish played 14 seasons for the Celtics before leaving, Ewing and Pierce played 15 seasons for the Knicks and Celtics before leaving, Olajuwon and Tony Parker played 17 seasons for the Rockets and Spurs before leaving, and Karl Malone spent 18 years with the Jazz before leaving, which is also the longest record, and they all missed out on one game at the club.
