Thompson spent his sophomore and half his junior year at St. Benedict's, making an immediate impact and showing flashes of brilliance.[3] In his short time there, he shot through the ranks to super-stardom, becoming the top recruit in the nation entering his junior season.[4] The nation's top basketball programs heavily sought Thompson, who made the first verbal commitment of the class of 2010 to Rick Barnes and the Texas Longhorns.[5]
Twenty-one games into his junior year, the relationship between Thompson and then-St. Benedict's coach Dan Hurley hit a rough patch. Hurley's in-your-face, no-holds-barred coaching style took a toll on the young star. During a game against then-top-ranked Mater Dei, Hurley confronted Thompson during a time out. A heated debate ensued, and Thompson was sent off the court and later removed from the team.[6] Over the next few days he made it known that he was planning to leave, resulting in a barrage of calls from top prep schools throughout North America trying to acquire his services. The next week he transferred to Findlay Prep with his close friend and AAU teammate Cory Joseph.[7][8]
Thompson joined Findlay on the back end of their schedule, making an immediate impact on the team and thriving under Findlay coach Michael Peck's system and coaching style. Thompson solidified his top recruit status and helped lead Findlay to their first national championship. He continued to round and polish his skills in his senior year in preparation for college and held fast to his commitment to the University of Texas, officially signing his letter of intent on November 11, 2009.[9] Thompson then led his team to another National Championship at the ESPN National High School Invitational.[10] After their senior year, Thompson and Joseph both committed to Texas and were the fourth and fifth Canadians to be named McDonald's All-Americans, after Bill Wennington (1981), Barry Bekkedam (1986) and Olu Famutimi (2003).[11] Thompson was also named a Jordan Brand Classic All-American.[12]
College career
Thompson averaged 13.1 points and 7.8 rebounds per game for the Texas Longhorns in 2010–11 as he won the team's Most Valuable Player award, as voted on by his teammates. Nationally, Thompson was one of five finalists for the Wayman Tisdale Award, an honour given to the National Freshman of the Year by the U.S. Basketball Writers Association. Thompson won the Big 12 Freshman of the Year honours as well as first-team NABC All-District 8 and USBWA All-District VII honours.[13] He led the team in rebounding, blocked shots (86), double-doubles (10) and field goal percentage (.546) while ranking second in scoring. He helped Texas conclude the 2010–11 season with a 28–8 record and advanced to the NCAA Tournament Round of 32. The Longhorns finished No. 8 in the final AP poll.[14]
Thompson told media after the NCAA tournament that he planned to return to Texas for his sophomore season but changed his mind.[15] On April 21, 2011, he declared for the NBA draft, forgoing his last three years of college eligibility.[16]
Professional career
Cleveland Cavaliers (2011–2020)
2011–12 season: Rookie season
On June 23, 2011, Thompson was drafted fourth overall in the 2011 NBA draft by the Cleveland Cavaliers. At the time, he was the highest drafted Canadian-born player in NBA history,[17] that was until Anthony Bennett and Andrew Wiggins were selected as the first overall pick in 2013 and 2014, respectively. Thompson continued to make history, drafted alongside Joseph, who was picked 29th by the San Antonio Spurs, only the second occasion in NBA history to that date that two Canadians were selected in the first round of the same draft, the first being in 1983 when Leo Rautins and Stewart Granger were selected 17th and 25th respectively.[18] The 2011 draft was also the first time three Texas Longhorn basketball players went in the first round of a draft, when Thompson's former collegiate teammate Jordan Hamilton went 26th overall to the Dallas Mavericks.[19][20]
During the 2011 NBA lockout, Thompson attended classes at the University of Texas to finish his college degree.[21] Thompson signed his rookie contract with the Cavaliers on December 9, 2011, before the start of training camp.[22] Thompson made his professional debut against his hometown Toronto Raptors on December 26, 2011. In 17 minutes off the bench, Thompson scored 12 points and pulled in 5 rebounds.[23] Both Thompson and teammate Kyrie Irving were later named to the 2012 Rising Stars Challenge. However, Thompson was selected to play for Team Shaq, while Irving was selected by Team Chuck.
Thompson finished the season with averages of 8.2 points and 6.5 rebounds in 60 games as he earned NBA All-Rookie Second Team honors, becoming the first Canadian to ever earn All-Rookie team honors in the NBA.
2012–13 season
In the 2012–13 season, Thompson worked on avoiding getting his own shots blocked, and switched his shooting hand from left to right.[24] For most of the season, almost 17%, or one out of six, of his shots were blocked,[a] threatening former NBA player Danny Fortson's 16.7% rate in 1997–98. Thompson dropped to around 15% by season's end, which was only reached by three other players before the season.[b][25] He went on to average 3.7 offensive rebounds per game, which ranked fifth in the NBA and first among second year players, and set the Cavaliers franchise record for most offensive rebounds in a single season with 306 (second in the NBA), surpassing Zydrunas Ilgauskas' 299 offensive rebounds in the 2004–05 season. He also recorded a team-high 31 double-doubles on the season, becoming just the ninth player in franchise history to total at least 30 double-doubles in a single season. He started all 82 games in 2012–13 as he averaged 11.7 points on .488 shooting, 9.4 rebounds and 0.9 blocks in 31.3 minutes per game.[26]
2013–14 season
In the 2013 off-season, Thompson decided to switch his shooting hand to his right instead of his left.[27] Despite the change, he had an almost identical season for the Cavaliers in 2013–14, as he started all 82 games while averaging 11.7 points and 9.2 rebounds in 31.6 minutes per game. He tied for fifth in the Eastern Conference with a team-leading and career-best 36 double-doubles.[26]
2014–15 season
During the 2014 off-season, the Cavaliers acquired All-Star forwards LeBron James and Kevin Love. Thompson came off the bench for most of the season, providing energy and solidifying his place as one of the best offensive rebounders in the league, averaging 8.5 points and 8 rebounds per game. He played in all 82 games and started 15. The Cavaliers finished with a 53–29 record and made the playoffs for the first time since 2010. Early in the first round, Kevin Love dislocated his shoulder and was ruled out for the rest of the post-season. Thompson became the starter after Love's injury and helped the Cavaliers reach the 2015 NBA Finals. The Cavaliers faced the Golden State Warriors, and lost the series in six games. During the playoffs, Thompson emerged as one of the NBA's best rebounders, especially on the offensive glass. He became a restricted free agent after the season.[28]
2015–16 season: Championship season
On October 22, 2015, Thompson re-signed with the Cavaliers on a five-year, $82 million contract, ending a four-month contract stalemate that caused Thompson to miss training camp, the preseason, and the FIBA Americas Championship.[29][30][31] Throughout the 2015–16 season, Thompson shared the starting center role with Timofey Mozgov. On January 25, 2016, he recorded a season-high 19 points and 12 rebounds in a 114–107 win over the Minnesota Timberwolves.[32] On March 26, in a win over the New York Knicks, Thompson tied Jim Chones' franchise record by appearing in his 361st consecutive game for the Cavaliers.[33] He broke that record three days later, appearing in his 362nd consecutive game in a loss to the Houston Rockets.[34] Thompson helped the Cavaliers reach the NBA Finals for the second consecutive season. There they made NBA history by coming back from a 3–1 deficit against the Golden State Warriors to win the series in seven games, ending a 52-year championship drought in Cleveland.[35][36]
2016–17 season
On December 26, 2016, in a loss to the Detroit Pistons, Thompson became the first player in franchise history to play in 400 consecutive regular-season games.[37] On April 5, 2017, Thompson missed the Cavaliers' game against the Boston Celtics with a sprained right thumb. Thompson's absence ended his streak of consecutive games played at 447—the longest in team history and the longest active streak in the league at the time.[38] He missed four games with the injury before returning to action in Cleveland's regular-season finale on April 12 against the Toronto Raptors.[39] Thompson helped the Cavaliers go 12–1 over the first three rounds of the playoffs to reach the NBA Finals for a third straight season. There the Cavaliers matched-up with the Golden State Warriors, but lost the series in five games.[40][41]
2017–18 season
On November 2, 2017, Thompson was ruled out for three to four weeks with a left calf strain that he suffered the previous night against the Indiana Pacers.[42] On December 12, 2017, he played in his first game since November 1; he went scoreless and did not have a rebound in 6 minutes against the Atlanta Hawks.[43] On February 25, 2018, he had a season-high 13 rebounds in 23 minutes in a 110–94 loss to the San Antonio Spurs.[44] In Game 7 of the Cavaliers' first-round playoff series against the Pacers, Thompson, who played just 24 minutes in the first six games, made a rare start and had 15 points and 10 rebounds in a 105–101 win.[45] The Cavaliers made it to the 2018 NBA Finals, where they were swept by the Golden State Warriors.
2018–19 season
To begin the season for the 6–21 Cavaliers, Thompson was averaging career highs in points (12.0) and rebounds (11.6) through 27 games.[46] However, on December 11, he was ruled out for two to four weeks with a left foot sprain.[47] He returned to action on January 2 against the Miami Heat after missing 10 games.[48] On March 20, against the Milwaukee Bucks, Thompson returned after missing 26 games with a sore left foot.[49]
2019–20 season
On January 9, 2020, Thompson recorded a double-double with a career-high 35 points, 14 rebounds, three assists, three blocks and a steal in a 115–112 overtime win over the Detroit Pistons.[50]

Thompson has had an on-again, off-again relationship with Khloé Kardashian. They initially began dating in 2016 when he allegedly cheated on his pregnant ex-girlfriend Jordan Craig with Kardashian, according to court documents.[75][76] On April 12, 2018, Khloé gave birth to their daughter, True, amidst controversy after Thompson was found to have cheated on Kardashian during the pregnancy.[77][78][79][80] In February 2019, Thompson and Kardashian split after it was revealed that Thompson had allegedly cheated on Kardashian with her younger half-sister Kylie Jenner's then-best friend Jordyn Woods.[81][82] Thompson and Kardashian quarantined together during the COVID-19 pandemic, and subsequently resumed their relationship from summer 2020 to June 2021,[83] as well as October to December 2021.[84] On July 28, 2022, Kardashian and Thompson welcomed their second child, Tatum,[85] via surrogate.[86]
