Parker was born in Brooklyn to parents William "Bill" Henry Parker II and Robin Royal Parker.[1] He attended Newtown High School in Elmhurst, Queens, where he was a star guard on their varsity basketball team.[2] He then enrolled in the College of Southern Idaho as a freshman in the 1999–2000 season and transferred to play college basketball at Fordham University.[3] Following his sophomore season at Fordham University, he entered the NBA in 2002 but went undrafted.[4] During his sophomore season, he was Second Team All A-10 and Second Team NABC All-Region.[5]
He then signed a contract with the Los Angeles Lakers during the summer of 2005.
Not well-known entering the 2005 season, Parker gained recognition as the starting point guard for the Lakers under coach Phil Jackson. While many experts thought that either newly signed veteran Aaron McKie or Sasha Vujačić would start at point guard, Parker became the surprise starter in the Lakers' season opener against the Denver Nuggets[7] and went on to score at least 20 points in four of his first five games.[8][9] This impressed Jackson, and Parker found himself in the starting line-up for the Lakers. From 2005 until 2007, Parker started 162 straight games, averaging 11.5 points. During the last two games of the regular season and the playoffs (2006–2007), Parker lost his starting spot to rookie Jordan Farmar.
While with the Lakers, Parker clashed with Kobe Bryant. Bryant singled out Parker as a bad teammate, saying in 2012 that Parker "shouldn't have been in the NBA, but [the Lakers] were too cheap to pay for a point guard."[10] Parker would later detail how Bryant was a bad teammate, and after Bryant's death in 2020, confirmed that the two men had never reconciled their differences.
Later NBA and overseas career
On July 26, 2007, Parker signed with the Miami Heat.[11] For the Heat, Parker wore jersey number 21.[12] His production dropped off dramatically while with the Heat, with averages of 4.8 points, 1.7 assists and 2.1 rebounds, compared to his 11.1 in 164 games with the Los Angeles Lakers.[4] After a physical altercation that Parker had with a parking attendant in November 2007, the Miami Heat put him on paid leave to investigate the matter.[13] On March 10, 2008, the Miami Heat officially waived Parker.[14] The Los Angeles Clippers then signed him for the rest of the season on March 12, 2008.[4]
On July 10, 2008, the Los Angeles Clippers officially renounced their rights to Parker.[15] In the 2008 offseason, Parker was signed by the Denver Nuggets but was released on October 23, 2008, as the Nuggets trimmed their roster to the league-allowed 15. He then played with the Rio Grande Valley Vipers of the NBA Development League.
Parker never played in the NBA after the 2007 - 2008 season with the Clippers and thus his final NBA game ever was played on April 16, 2008, in a 75 - 93 loss to the Houston Rockets. In his final game, Parker recorded 9 points, 2 rebounds and 2 assists.
In March 2013, he returned to Greece and signed a contract with Peristeri of the Greek League.
In January 2014, he signed with his former team Guaros de Lara.[23] He left the team that March.[24] In June, Parker played in The Basketball Tournament.[25] His team reached the semi-finals,[26] and Parker's averages for the tournament were 16.2 points, 7.8 rebounds, 7.0 assists and 1.8 steals per game.[27]
In February 2015, Parker signed with Mon-Altius Madimos Falcons of the Mongolian National Basketball Association (MNBA). He averaged 24 points, 7.0 rebounds, 6.5 assists and 4.1 steals per game.
Parker earned his nickname "Smush" at birth from his mother. "Smush" was a term of endearment for his father, so he became Baby Smush at birth.[29] Parker has one daughter from a previous relationship.[1] Parker is currently married.[citation needed]
