Anunoby had the best season of his career with the Raptors in 2020-21. In 33.3 minutes per game across 43 appearances, he averaged 15.9 points, 5.5 rebounds, 2.2 assists and 1.5 steals. He shot 48.0 percent from the field, 39.8 percent from three and 78.4 percent from the free-throw line. During the third game of the season, which was against the 76ers, Anunoby recorded a season-high five steals. In a win over Dallas on Jan. 18, Anunoby grabbed a season-high 11 boards. Six days later in a win over the Pacers, he scored a season-high 30 points. Against the Pistons on March 29, the forward blocked a season-high three shots. On April 8 against Chicago, Anunoby recorded a career-high six assists. He had three double-doubles. He had 13 appearances with at least 20 points, 31 games with at least five rebounds and three games with at least five assists. He also had at least three steals in nine games and multiple blocks in six games.

Anunoby enjoyed a major increase in playing time in his third NBA season, and he rewarded the Raptors with the finest statistical output of his career. He started 68 of his 69 appearances in the coronavirus-shortened 2019-20 campaign, setting career highs with 29.9 minutes per game, 10.6 points, 1.3 threes, 5.3 rebounds, 1.4 steals, a 50.5 field-goal percentage and a much-improved 70.6 free-throw percentage. There were plenty of single-game highs as well. Anunoby posted a career-high 32 points on 12-of-16 shooting with a career-high seven steals Mar. 1 against Denver. The British-born forward set a new career high in rebounds with 12 on Nov. 27, then matched that mark three more times over the course of the year. He also notched a career-high four blocks on two occasions. Anunoby remained in the starting lineup come playoff time, delivering a well-rounded stat line with averages of 10.5 points, 6.9 rebounds, 1.2 blocks and 1.0 steals across 11 games. In Game 2 of the second round against Boston, he set a playoff career high with 20 points. In Game 3 of that series, Anunoby posted 12 points and 10 rebounds, including hitting a buzzer-beating three-pointer to win the game. He double-doubled again with 13 points and 13 boards in Game 6.

Anunoby's sophomore season was full of ups and downs. His strong play resulted in an invitation to participate in the Rising Stars Challenge in February, where he scored 12 points in 18 minutes for Team World. However, multiple ailments, including a wrist injury and a concussion, limited the Indiana product to 67 games during the regular season. If that wasn't enough, a late-season appendectomy wiped out Anunoby's entire postseason. When he did play, the 6-foot-8 forward posted per-game averages of 7.0 points and 2.9 rebounds. He converted 45.3 percent of his field goal attempts, including 33.2 percent of his shots from behind the arc. Anunoby also made 58.1 percent of his free-throw attempts. A four-game stretch from Nov. 5 to Nov. 12 in which he averaged 15.3 points per game was undoubtedly the most impressive run of Anunoby's young career. He also chipped in a 21-point game in mid-December and a 22-point game in mid-February. Anunoby averaged one made three-pointer in addition to one steal-plus-block per game in 20.2 minutes worth of action, so he can contribute in a variety of areas.
