[1] Smith was selected out of Chicago's Martin Luther King High School (where he averaged 25.5 points and 14.5 rebounds per game in his senior year)[2] by the San Antonio Spurs in the first round (29th overall) of the 1999 NBA draft, and was immediately traded to the Dallas Mavericks in exchange for the draft rights to Gordan Giriček and a second-round pick in the 2000 NBA draft.

However, in subsequent months he suffered numerous psychological concerns, and was released in February 2000 without ever playing a game for the Mavericks.

[3] A month previous, Smith was released from a psychiatric ward to where he was committed for several weeks, after an incident in which he threw a rock through a car window and swallowed approximately 250 aspirin tablets and would tell police officers, "I am an Indian fighting Columbus".

His short stint with the Hawks involved being waived, signed back a second time, and eventually being traded to the Milwaukee Bucks, for whom he never played.

[5] Late in the 2003–04 NBA season, the Seattle SuperSonics signed Smith to a contract,[7] but he only played one game for them.
