[2] Born in Syracuse, New York, he became a naturalized Filipino citizen on March 11, 2011, thus allowing him to play for the Philippines' men's national basketball team.

The school is primarily known for its basketball program, which has produced notable players such as Michael Beasley, Paul Harris, Lazar Hayward, and Derrick Caracter, to name a few.

[7] However, he decided to play ball in Belgium instead since the Lakers already had 15 players on the roster, and it was still awaiting the decision of Karl Malone if he would join the team.

[10] Douthit along with other aspirants such as J. R. Pinnock, Mamadou N'diaye, and Devin Green were all cut by the Lakers before the start of the regular season.

[11] The Los Angeles Clippers, on the other hand, signed Douthit and Jamaican professional basketball player Kimani Ffriend in the 2007–08 NBA season, including them in the team's training camp roster.

Playing under coach Michael Cooper, he was part of the team's starting lineup along with Tony Bland, T. J. Cummings, Andreas Glyniadakis, and Tierre Brown.

[18] After several stints in a number of professional leagues in Europe, Douthit suited up for BC Krasnye Krylya Samara in Russia.

[20] In May 2010, Samahang Basketbol ng Pilipinas announced that Douthit has been invited to try out for a spot in the Philippines men's national basketball team, Smart Gilas.

[22] On February 25, 2011, he scored 16 points and collected 26 rebounds in his debut game with Gilas in the Philippine Basketball Association against the Talk 'N Text Tropang Texters.

[27] On January 3, 2017, it was reported that Douthit signed a contract to play for the Hanoi Buffaloes, a Vietnamese ball club which will compete at the Thailand Basketball Super League.

Douthit first suited up as an import for Gilas at the 2010 MVP Invitational Champions' Cup, which was held from June 24 to 27 at the Ninoy Aquino Stadium.

Toroman, a former assistant coach of the national squad of Yugoslavia from 1991 to 1995, was impressed with Douthit's performance and recommended him to be Gilas’ top prospect for naturalization.

[33] In June 2010, the Samahang Basketbol ng Pilipinas (SBP) announced that Douthit agreed to sign a one-year contract and undergo the naturalization process.

[34] After the process, he would be allowed to represent the Philippines as a full-fledged Filipino in international competitions such as the 2011 FIBA Asia Championship, a qualifying tournament of the 2012 Summer Olympics in London.

Douthit's represented the Philippines at the 2010 William Jones Cup, an international basketball tournament held from July 14 to 22 in Taipei, Taiwan.

[35] Because he and Gilas teammate Chris Lutz have not secured a Filipino passport in time for the competition, Douthit did not suit up for the team at the FIBA Asia Stanković Cup 2010, held from August 7 to 15 in Beirut, Lebanon.

[39][40] In that year's FIBA Asia Championship, he averaged 21.9 points and 12.2 rebounds for Smart Gilas, which finished fourth overall in the tournament.

"[47]In February 2011, former Samahang Basketbol ng Pilipinas executive director Noli Eala announced that Douthit's application for Filipino naturalization has already been transmitted for signature to the office of Philippine President Benigno Aquino III.

10148 [49] introduced by Antipolo Second District Congressman Robbie Puno, which grants Filipino citizenship to Douthit, lapsed into law after President Aquino failed to sign it.

During the 2019–20 season, Douthit joined the coaching staff of the Community College of Rhode Island (CCRI) Knights basketball team.
