Kemba Walker attended Rice High School in Harlem, New York. Kemba had a great high school career and had his name in bright lights when he faced off against Derrick Rose’s Simeon High School at Madison Square Garden. Kemba's Rice High School defeated Rose’s team by a score of 53-51 in his junior year.

The following season, Walker had one last chance to prove to scouts he was the real deal. As a senior, Walker averaged 18.2 points and 5.3 assists per game. These statistics were enough to land him a spot on the McDonald’s All-American Team. Kemba Walker was listed as a 5-Star Recruit coming into college and was ranked No. 5 in his position and No. 14 overall in the class. 

The University of Connecticut is where the star was born. Walker's step-back buzzer-beating jump shot to lift the Huskies over the Pittsburgh Panthers in the 2011 Big East Tournament etched his name in history. But, where did it all begin? As a freshman at UConn, Walker played in every single game for the Huskies. He was named to the Big East All-Rookie Team. He was not a starter, but he played 25.5 minutes per game, and the Huskies landed a number one seed in the 2009 NCAA Tournament. Kemba dropped 23 points in an Elite Eight win against Missouri, but the Huskies were defeated in the Final Four. 

As a sophomore in the 2009-10 season, Walker was now a full-time starter. He averaged 14.6 points on the season, but this year UConn declined and only reached the 2019 National Invitation Tournament. However, the disappointing 18-16 season in his sophomore year seemed to inspire Kemba. As a junior, Kemba became a star. He led the nation in scoring with 26.7 points, and he also added 5 rebounds and 3.8 assists per game. Kemba hit the memorable game-winner against the Pittsburgh Panthers in the 2-11 Big East Tournament that gave him global notoriety. That year, Kemba Walker became a National Champion as he led the Huskies to a win with 16 points in the National Championship Game versus the Butler Bulldogs.

He was also named the Most Outstanding Player of the tournament.

On April 12, 2011, Kemba Walker announced that he would be foregoing his senior season at UConn and entering his name into the 2011 NBA Draft. That year he was selected ninth overall by the Charlotte Bobcats, and immediately signed an endorsement deal with Under Armour. After inking his name with the Bobcats on December 11, 2011, Walker quickly got a chance to play. With starting point guard D.J. Augustin out with injury, Walker got a chance to start at point guard. His first big night came against the Washington Wizards where he tallied his first triple-double with 20 points, 11 assists, and 10 rebounds on the January 28 affair. 

Walker’s 2012-13 season showed improvement as he averaged 17.7 points, 5.7 assists, 3.5 rebounds, and 2 steals per game. He also hit his first game-winner of his NBA Career that season to lead the Bobcats over the Minnesota Timberwolves on November 14, 2012. On December 9, 2013, Walker proved he was a pure scorer in this league. He poured in 31 points, with 27 points in the second half in a victory over the Golden State Warriors. Walker took over, scoring the last 15 points of the game. The following season in 2014-15 was another strong one for Walker, but he did manage to tear his lateral meniscus in his left knee, causing him to miss six weeks. 

In the 2015-16 season, Walker started off hot with a 39 point barrage in a win over the Sacramento Kings on November 23, 2015. That season he also became the third Hornets player to make 500 career three-pointers, adding his name to a shortlist of Dell Curry and Glen Rice. Walker also proved he was a playoff scorer too, scoring 34 and 37 points in various games of a first-round affair with the Miami Heat. 

2017-18 marked the first season that Walker became an NBA All-Star. On March 28, 2018, he became the franchise leading scorer, topping Dell Curry’s 9,839 points. The next season would mark Walker's last in Charlotte. In 2019, Walker Walker was sent to the Boston Celtics in a sign-and-trade deal centered around Kyrie Irving. In his debut with the Boston Celtics, he tallied just 12 points but followed that up with a 39 point explosion a few weeks later over the Brooklyn Nets. He also managed to tally an individual feat, as he earned his first victory over LeBron James this year. He was previously 0-28 against LeBron.

As a new member of the Boston Celtics, Walker was named an NBA All-Star for the fourth straight year.
