Collison played four seasons of college basketball for the UCLA Bruins. He earned All-Pac-10 conference honors three times, and won the Frances Pomeroy Naismith Award his senior year as the top college player 6 feet (1.8 m) and under. He was drafted by the Hornets in the first round with the 21st overall pick of the 2009 NBA Draft. Collison also played for the Indiana Pacers and Dallas Mavericks.
Collison was born in Rancho Cucamonga, California to parents Dennis and June (Griffith), who were both elite track and field athletes for Guyana.
He chose to attend UCLA over San Diego State. He was a backup to Jordan Farmar in the Bruins' 2005–06 season, becoming the starting point guard the following season. He was awarded the MVP of the Maui Invitational Tournament in December 2006 and was named the Pacific-10 Conference Player of the Week on December 4, 2006, and again on February 18, 2007. During the 2006–07 season, Collison averaged 2.2 steals per game—the most in the Pacific-10 Conference. He also averaged 5.7 assists (2nd in the Pac 10), as well as a three-point shooting percentage of 44.7 percent.
Collison returned to UCLA for his junior and senior years and ended up playing in a total of 142 games at UCLA, tied for the most ever. In his senior year in 2008–09, he was named to the All-Pac-10 team after averaging 14.4 points, 4.7 assists, and 1.6 steals per game. He led the conference in free throw percentage, and was third in assists, steals, and assists-to-turnover ratio. Collison won the Frances Pomeroy Naismith Award that year, awarded to the best college player 6 ft 0 in (1.83 m) or shorter. He was also named the Bruins' co-Most Valuable Player (MVP) along with Josh Shipp. Collison and fellow senior teammates Shipp and Alfred Aboya finished their careers as the winningest class in UCLA history with 123 wins. The distinction was relative, as John Wooden's legendary teams played shorter seasons and freshmen were ineligible.
Collison was widely considered to be one of the top point guard prospects in the 2009 NBA Draft coming out of UCLA.He was selected in the first round with the 21st overall by the New Orleans Hornets.
With Chris Paul out for months at two separate times during the 2009–2010 season, Collison became the starting point guard. Collison handed out a Hornets rookie-record 18 assists and scored 17 points on January 30, 2010 when New Orleans ended Memphis's 11-game home winning streak with a 113–111 overtime victory. Later on March 8, 2010, Collison broke his own record with a Hornets rookie-record 20 assists (along with 16 points) in a 135–131 victory over the Golden State Warriors. In a game against the Indiana Pacers on February 19, 2010, Collison became only the second rookie of the 2009–2010 season to get a triple-double with 18 points, 13 rebounds, and 12 assists. He finished 4th in the NBA Rookie of the Year voting and averaged 18.8 points and 9.1 assists, but had four turnovers a contest as a starter in his first NBA season. On August 11, 2010, the Hornets traded Collison and James Posey to the Indiana Pacers in a four-team, five-player deal that also sent Troy Murphy to the New Jersey Nets, Trevor Ariza to the New Orleans Hornets and Courtney Lee to the Houston Rockets.
On July 12, 2012, Collison and Dahntay Jones were traded to the Dallas Mavericks for Ian Mahinmi. Collison became the Mavericks' starting point guard, replacing Jason Kidd who left as a free agent. Collison was a key player in Dallas' 4–1 start in 2012–13, but he struggled as they lost 8 of their next 11. After starting the team's first 14 games, Collison came off the bench for one game. He missed the next game with a sprained right middle finger, prompting Dallas to sign Derek Fisher. Fisher started in his first game with the Mavericks, while Collison remained a reserve. 14 games later, on December 27, 2012, he regained the starting job.
On July 10, 2013, Collison signed a deal with the Los Angeles Clippers.
