Lucas was the first overall pick of the
1976 NBA draft, selected by the
Houston Rockets. He was also drafted by the
New York Nets of the
American Basketball Association. Lucas played in the
NBA for fourteen years. Lucas initially played for the Rockets for two years before NBA commissioner
Larry O'Brien awarded him to the Golden State Warriors as compensation for the Rockets signing
Rick Barry as a free agent. While a member of the
Golden State Warriors, on October 20, 1978, Lucas scored a career-best 35 points during a 111–108 win over the Trail Blazers. In his last season with the Warriors, Lucas's problems began when he missed a series of practice sessions, plane trips and games. The Warriors suspended Lucas and chose not to pick up his contract option. Lucas played professional tennis and minor league basketball before returning to the NBA with the San Antonio Spurs and then moving on to Houston. Lucas's drug problems continued to plague him, and the Rockets waived him in 1984 and reinstated him the next season after he underwent rehabilitation. Lucas became a regular season starter for the
1986 Houston Rockets. However, after failing two drug tests, the Rockets waived Lucas in March before they embarked on a playoff run to the
1986 NBA Finals. Lucas played four more years in the NBA, averaging at age 33 a career-high 17.5 points for Milwaukee in 1986–87, after which, on May 8, 1987, he scored a team high 30 points to lead the Bucks to an Eastern Conference Semifinals Game 3 win over the Boston Celtics. The Bucks would go on to lose the series in seven games. Lucas played more of a reserve role for the next three years. Lucas played three games with the
Wichita Falls Texans in the
Continental Basketball Association (CBA) during the 1991–92 season. He was serving as head coach of the Miami Tropics in the
United States Basketball League (USBL) at the time and appeared to help his player,
Roy Tarpley, who was scared about making his debut after leaving a drug treatment facility. Lucas has helped multiple professional athletes with substance abuse, including
Freeman Williams, with whom he became close friends. ==Career statistics==
