But his disappointment has more to do with his legacy than missing out on a potential five-year, $221-million super-max deal.
"The money's nice, but I'm just trying to build a resume," Thompson told reporters at NBA Finals media day, according to ESPN. "And I see some other guys who played my position growing up, you know, the Ray Allens, Reggie Miller, Chris Mullin; I try to be in that mold. They made, you know, three, four All-NBA teams - I'm trying to get to that level."
Thompson received three second-team votes and 18 third-team votes to finish 24 points behind Charlotte Hornets' Kemba Walker for the final guard position on the All-NBA third team. While the five-time All-Star would've loved to have added a third career All-NBA team selection to his resume, he's appreciative of the chance to earn his fourth ring in five seasons.
"I just wanted to make that team so badly just because it's a huge honor thing, you know," Thompson said. "Being recognized as a top-15 player in the best basketball league in the world, that's amazing. But like I said before, the opportunity to win a championship is greater."
Thompson averaged 21.5 points on 46.7 percent shooting from the floor - including 40.2 percent from distance - across 78 regular-season appearances. He was recently voted to the NBA All-Defensive second team.
