James Monroe Jeffries III (born April 8, 1968) is a retired American basketball player best known for playing power forward for the Milwaukee Bucks from 1989-2005, the only team he was ever a part of. Jeffries was part of a group of Bucks players that formed the "Breakout Bucks" of the mid-1990s, winning NBA championships in 1994 and 1996 as part of one of the highest-scoring offenses in NBA history. In 1997, the Bucks brought in three highly-touted defensive players and he became more of a defensive contributor, winning Defensive Player of the Year in 1999 and helping lead the Bucks to a third championship that year. He continued to consistently perform for the Bucks even after the trade of teammate Will Smith in 2000 and the free-agency departure of Mike Ford in 2003, before retiring after the 2004-05 season.
Jeffries played college basketball at Kentucky, where he was a star player, winning AP Freshman of the Year in 1986-87 and the Naismith Award and AP Player of the Year in 1988-89. He left the school after his junior season and was the No. 1 overall pick in the 1989 NBA Draft. His number 32 is retired both at Kentucky and in Milwaukee.
Jeffries was born in Miami, Florida to James M. Jeffries, Jr. and Lola Edwards. Jeffries grew up in a violent neighborhood - his younger brother Richard was killed while in middle school during a drive-by shooting.
