DeMarcus Amir Cousins (born August 13, 1990) is an American professional basketball player for the Los Angeles Lakers of the National Basketball Association (NBA). Nicknamed "Boogie",^[1] he played college basketball for the Kentucky Wildcats, where he was an All-American in 2010. He left Kentucky after one season, and was selected with the fifth overall pick in the 2010 NBA draft by the Sacramento Kings. In his first season with the Kings, Cousins was named to the NBA All-Rookie First Team, and from 2015 to 2018, he was named an NBA All-Star. He is also a two-time gold medal winner as a member of the United States national team, winning his first in 2014 at the FIBA Basketball World Cup and his second in 2016 at the Rio Olympics.

Cousins attended LeFlore Magnet High School in his hometown of Mobile, Alabama.^[2] He was a first-team Parade All-American in 2009, and played in the 2009 McDonald's All-American Boys Game, finishing with 14 points and 8 rebounds.^[3] Cousins also played in the 2009 Nike Hoop Summit at the Rose Garden in Portland and the Jordan Brand Classic at Madison Square Garden where he scored 10 points for the black team.^[4] Cousins led LeFlore to the Alabama class 6A Final Four against Hillcrest that beat Austin High School to progress to the state championship; falling short to future college teammate Eric Bledsoe and Parker High School.

Cousins first committed to Alabama-Birmingham on February 28, 2008, but never signed a letter of intent.^[5] Cousins decommitted from UAB and committed to Memphis on March 9, 2009.^[6] He reopened his recruitment after then Memphis coach John Calipari was hired at Kentucky. On April 7, 2009, Cousins decided to follow John Calipari to Kentucky.^[7] He signed his letter of intent on April 15. At Kentucky, Cousins averaged 15.1 points, 9.8 rebounds and 1.8 blocks per game. Led by Cousins and John Wall, the Wildcats reached the Elite Eight of the 2010 NCAA Tournament.

On April 7, 2010, Cousins announced that he would forgo his final three seasons of collegiate eligibility and enter the 2010 NBA draft, where he was selected by the Sacramento Kings with the fifth overall pick.^[2] On July 7, 2010, Cousins signed his rookie contract with the Kings, worth about $7 million for the first two years with a team option for the third and fourth years.^[9] Cousins was named the Rookie of the Month for July during the NBA Summer League.^[10] Cousins was also named to the NBA All-Rookie First Team at the end of the 2010–11 season.

On January 1, 2012, head coach Paul Westphal sent Cousins home from the Kings' home game against the New Orleans Hornets, saying that Cousins was "unwilling/unable to embrace traveling in the same direction as his team; it cannot be ignored indefinitely."^[11] Cousins, who had been averaging 13.0 points and 11.3 rebounds per game at the time of the dismissal, reportedly demanded to be traded from the Kings. Cousins later denied asking to be traded.

On January 5, 2012, Westphal was fired from the Kings, leading many to speculate that the head coach's tumultuous relationship with Cousins was a factor in his being replaced.^[12] On February 8, 2012, Cousins was selected to play in the Rising Stars Challenge. He played for Team Chuck, with a mix of rookies and sophomores.

On November 11, 2012, the league suspended Cousins for two games without pay for confronting San Antonio Spurs color commentator Sean Elliott "in a hostile manner" after he criticized Cousins for attempting to bully Tim Duncan on the court.^[13] Cousins was apparently informed of Elliott's remarks after the game. He left the locker room and waited on the court for Elliott to finish his post-game show before confronting him. Some criticized the suspension as overly harsh and based more on Cousins' reputation than what actually happened, while others said he needed to grow up and learn a lesson about confronting the media.^[14] Cousins apologized to Elliott in person before a game against the Spurs in March 2014, which Elliott said he appreciated.^[15]

On December 22, 2012, Cousins was suspended indefinitely from the Kings, who accused him of "unprofessional behavior and conduct detrimental to the team."

^[16] The suspension was lifted on December 24, 2012.^[17] The season was up-and-down for Cousins, who posted career-highs in Player Efficiency Rating, field goal percentage, and free throw percentage, but led the NBA with 16 Technical Foul infractions, was ejected several times and suspended by both the league and the Kings.

After averaging career-highs of 23.5 points, 12.6 rebounds and 1.5 blocks over the first 15 games of the season, Cousins was diagnosed with viral meningitis on December 7, 2014.^[21] He subsequently missed 10 games with the virus and showed no signs of a let up in his return to action on December 18 against the Milwaukee Bucks as he recorded 27 points and 11 rebounds in the 107–108 loss.^[22]

On January 30, 2015, Cousins was named to replace the injured Kobe Bryant as a Western Conference All-Star in the 2015 NBA All-Star Game. Cousins' selection marked the first time a Kings player earned All-Star honors since Brad Miller and Peja Stojaković represented Sacramento in 2004.^[23]

In the following game on April 3 against the New Orleans Pelicans, Cousins became the first Kings player to record back-to-back triple doubles since Chris Webber did so in 2005. In just under 42 minutes of action, he recorded 24 points, 20 rebounds and a career-high 13 assists in a 95–101 loss.
