Antoine Walker (born August 12, 1976 in Chicago, Illinois, USA) is a professional basketball player with the Miami Heat in the National Basketball Association. He has played for four different teams during his NBA career.
Walker grew up in Dolton, Illinois and went to Mount Carmel High School in Chicago, the same school as current several other professional sportsmen including Philadelphia Eagles quarterback Donovan McNabb, Chicago Bears tackle Steve Edwards, and Tampa Bay Buccaneers defensive end Simeon Rice. He was a key factor in the University of Kentucky Wildcats 1996 NCAA Men's Division I Basketball Championship-winning team. As a freshman at the University of Kentucky he was named SEC Tournament MVP. In his sophomore year Antoine was named All-SEC First, All-SEC Tournament and to the All-NCAA Regional Teams. After his sophomore season he declared for the 1996 NBA Draft and was picked sixth overall by the Boston Celtics. Walker later teamed with Paul Pierce to help Boston play at a relatively high level, and was selected to three NBA All Star Game appearances during this time.
Nine days before the start of the 2003-04 season, Antoine Walker was traded to the Dallas Mavericks. Walker was used in a relatively limited capacity on the his new team due to the plethora of high-caliber players populating the Mavericks' roster. Included on that team was Antawn Jamison, newly acquired from the Golden State Warriors. On August 8, 2004 Walker and Tony Delk were traded to the Atlanta Hawks for Jason Terry, longtime Hawks member Alan Henderson and a draft pick. On February 24, 2005, Walker was traded back to the Celtics in a deal that sent Gary Payton, Tom Gugliotta, Michael Stewart, and a first round draft pick to the Hawks. Gary Payton was released by the Hawks and re-signed with Boston for the remainder of the season.
On August 2 2005, Walker was involved in a 5-team, 13-player deal (the largest trade in NBA history) that sent him from the Celtics to the Miami Heat.
