Lamar began playing basketball for Christ the King Regional High School in Queens. He played for three years before shuttling between two more teams, first to Redemption Christian Academy and then to St. Thomas Aquinas High School in Connecticut. He later went on to attend the University of Nevada at Las Vegas and the University of Rhode Island.
In 1999, Lamar began his NBA career after being drafted by the Los Angeles Clippers. He went on to play for the Miami Heat, LA Lakers, and Dallas Mavericks and returned to the Clippers in 2012. He became a free agent the following year and signed with Laboral Kutxa of the Spanish ACB League, but was only able to play two games before being injured. Lamar moved back to the States, signing with the New York Knicks in February 2014 — but he was released just six months later.
Despite the bumps in his career, Lamar has won two NBA championships with the Lakers and helped the US national team win a bronze medal in the 2004 Olympic games in Athens.
