Background: Tyson Cleotis Chandler (born October 2, 1982) is an American professional basketball player for the Phoenix Suns of the National Basketball Association (NBA). Chandler was the second overall pick of the 2001 NBA draft by the Los Angeles Clippers, then was immediately traded to the Chicago Bulls. He has also played for the New Orleans Hornets, Charlotte Bobcats, Dallas Mavericks, and New York Knicks. As starting center for Dallas, he played an integral role in the franchise's first NBA championship in 2011.
Context: Chandler was born to Frank Chandler and Vernie Threadgill, though he did not meet his father Frank until later in his life. He grew up in a family farm in Hanford, California, just south of Fresno, California. Chandler began playing basketball at the age of three years on a basket Chandler's grandfather, Cleotis, fixed on a tree. Chandler grew up doing farm work such as milking cows, slopping pigs, and cultivating crops. At the age of nine years, Chandler and his mother moved to San Bernardino, California; he was already nearly six feet tall. As a child, Chandler was teased because of his height; children on his school basketball team joked that he was older than he really was, and that he had been left back several times in school.  Chandler and his family then moved to Compton, California, where he enrolled at Dominguez High School, a school known for its athletics, producing basketball players such as Dennis Johnson and Cedric Ceballos. In his freshman year, Chandler made the varsity team and played with future NBA player Tayshaun Prince, who was then a senior. With the Dominguez Dons, Chandler became a teenage sensation; current players such as DeMar DeRozan watched him play and claimed "he was like Shaq". Point guard Brandon Jennings, who was a ball boy for Dominguez at the time, said, "You'd see the girls around Tyson, the Escalade he drove, and you wanted to be like him". Chandler earned accolades from Parade Magazine and USA Today, and was selected to the McDonald's High School All-America Team. As a freshman, he was profiled on current affairs TV program 60 Minutes.  In his junior year, Chandler averaged 20 points, 12 rebounds, 6 assists and 3 blocks. In his senior year, Chandler led Dominguez to a state championship and a 31-4 record, averaging 26 points, 15 rebounds, and 8 blocks a game. Chandler was recruited by several universities and considered UCLA, Arizona, Syracuse, Memphis, Kentucky and Michigan. Chandler then declared for the 2001 NBA draft as a prep-to-pro.
