After suffering a torn ACL during the 2019 NBA Finals, Thompson ended up missing the entire 2019-20 season, although it took the Warriors until Feb. 20 to officially declare that he wouldn't return during the campaign. Then, on Nov. 19, 2020, the team announced that Thompson will miss the entire 2020-21 season after tearing his right Achilles tendon during a workout.

Thompson's eighth season in the league began in quiet fashion before he broke out with a 52-point outburst against Chicago on Oct. 29. The 52 points were a season high, but more impressive was the fact that he broke fellow splash brother Steph Curry's NBA record for three-pointers in a game by draining 14 from behind the arc. His 24 three-point attempts in that game also set a new single-game record. On Jan. 21, Thompson drained 10-of-11 three-point attempts in a win over the Lakers and finished with 44 points. In February, Thompson earned his fifth straight All-Star game nod. On Feb. 13, he dished out a season-high eight assists against Portland, matching a career-high. "Big Smokey" appeared in 78 regular season games, averaging 21.5 points, 3.8 rebounds, 2.4 assists and 1.1 steals. In 21 playoff games, Thompson averaged 20.7 points and 4.1 rebounds while shooting a playoff career-high 44.3 percent from three-point land. With Thompson's help, the Warriors reached their fifth straight NBA Finals. A hamstring injury forced Thompson to miss Game 3, but he returned for Game 4 and scored 28 points. During the decisive Game 6 loss, Thompson delivered 30 points before leaving the game early with an ACL tear. Thompson's knee injury was very serious and may force the guard to miss the 2019-20 season.

Thompson made his fourth consecutive NBA Finals appearance, winning his third Championship ring in the 2017-18 season. In 73 regular season games, he averaged 20.0 points, 3.8 rebounds and 2.5 assists while playing 34.3 minutes a game. He scored his 10,000th career point against the Los Angeles Clippers on Feb. 22 as part of a 19-point performance. He set career highs in shooting percentage, posting a career-best 44.0 percent mark from three-point range and 52.6 percent rate from inside the arc. Thompson scored at least 20 points on 38 different occasions during the regular season, including a stretch from Nov. 24 to Dec. 14 in which he reached the 20-point mark in 10 of 11 games. Thompson scored a season-high 38 points against Chicago on Jan. 17. The 27-year-old notched two double-doubles on the season: a 23-point, 10-rebound game against Brooklyn on Nov. 19 and a 17-point, 10-rebound effort against the Lakers on Dec. 18. Thompson scored 34 points in 34 minutes against the Suns on April 8. He scored a season playoff-best 35 points in a must-win Game 6 of the Western Conference Finals against Houston on May 26.

Thompson was selected to the Western Conference All-Star team for the third straight season and scored a career-high 12 points in the February competition. The veteran sharpshooter produced one of the most prolific games in NBA history against Indiana on Dec. 5, scoring a career-high 60 points in only 29 minutes of action. With the performance, he became the first player in NBA history to tally 60 points in less than 30 minutes. In the memorable effort, Thompson hit 21-of-33 field goals (including 8-of-14 shots from deep) and 10-of-11 free-throws. The Washington State product's strong season helped the Warriors win 67 games and enter the playoffs as the top seed in the Western Conference.

Thompson ranked second in the league to teammate Stephen Curry in total three-pointers made (276) for the third straight season. The pair combined for 678 treys, again shattering their own NBA record for three-pointers made by a duo on the same team. Thompson scored 40 points in consecutive games from March 25-27, the first time in his career he accomplished that feat. The 6-foot-6 guard was named to his second straight All-Star team and competed in his second consecutive Three-Point Shootout during All-Star Weekend. In the finale of the competition, Thompson defeated Curry and Devin Booker to become Three-Point Champion. The sharpshooting guard was also named to the All-NBA Third Team for the second straight season. With Curry injured for parts of the playoffs, Thompson stepped up to help lead Golden State to its second straight NBA Finals appearance. In Game 6 of the Western Conference Finals, he drilled an NBA playoff record 11 three-pointers en route to 41 points in a crucial victory. Though the Warriors ultimately fell to Cleveland in a rematch of the previous season's Finals, Thompson enjoyed a strong overall postseason, posting per-game averages of 24.3 points, 4.1 treys and 3.7 boards over 24 contests.

The 2014-15 campaign was magical both for Thompson and his Golden State Warriors. The 6-foot-6 guard played in 77 games and averaged 31.9 minutes per contest. He established career highs with per-game averages of 21.7 points, 3.2 rebounds and 2.9 assists.
