The 1976 NBA draft was the 30th annual draft of the National Basketball Association (NBA).
 The draft was held on June 8, 1976, before the 1976–77 season.
 In this draft, 18 NBA teams took turns selecting amateur U.S. college basketball players and other eligible players, including international players.
 The first two picks in the draft belonged to the teams that finished last in each conference, with the order determined by a coin flip.
 The Atlanta Hawks won the coin flip and were awarded the first overall pick, while the Chicago Bulls were awarded the second pick.
 The Hawks then traded the first pick to the Houston Rockets before the draft.
 The remaining first-round picks and the subsequent rounds were assigned to teams in reverse order of their win–loss record in the previous season.
 The New York Knicks forfeited their first-round draft pick due to their illegal signing of George McGinnis whose rights were held by the Philadelphia 76ers.
 The 76ers, the Golden State Warriors and the Buffalo Braves also forfeited their second, third and fourth-round pick respectively due to their participation in 1975 supplementary draft American Basketball Association (ABA) players who had never been drafted in the NBA.
 A player who had finished his four-year college eligibility was eligible for selection.
 If a player left college early, he would not be eligible for selection until his college class graduated.
 Before the draft, 26 college underclassmen were declared eligible for selection under the "hardship" rule.
 13 of them withdrew before the draft, leaving only 13 early entry candidates eligible for selection.
 These players had applied and gave evidence of financial hardship to the league, which granted them the right to start earning their living by starting their professional careers earlier.
 The draft consisted of 10 rounds comprising the selection of 173 players.
 On August 8, 1976, the league also hosted a Dispersal draft for ABA players from the Kentucky Colonels and Spirits of St. Louis, who were not included in the ABA–NBA merger.
Each year, "USA Today", an American newspaper, awards outstanding high school basketball players with a place on its male and female All-USA high school basketball teams.
 The newspaper names athletes whom it believes to be the best basketball players from high schools around the United States.
 In addition, one member of each team is named, respectively, the male or female USA Today High School Basketball Player of the Year.
 The newspaper names two teams, one for male athletes and one for female athletes.
 The newspaper has named a team every year since 1983.
 Each year, the newspaper also selects a USA Today High School Boys' Basketball Coach of the Year and a USA Today High School Girls' Basketball Coach of the Year.
The 1997 WNBA draft was the inaugural draft held by the WNBA through which teams could select new players from a talent pool of college and professional women's basketball players.
 Unlike later drafts, this draft was unique because there were three different stages in which teams built their rosters.
 First on January 22, 1997, the Initial Player Allocation draft took place in which 16 players were assigned to each team in no particular order.
 The elite draft portion comprised professional women's basketball players who had competed in other leagues, usually international leagues.
 On February 27, 1997, an elite draft added two more players to each team.
 On April 28, 1997, the four rounds of the regular WNBA draft took place.
 Draftees Cynthia Cooper, Sheryl Swoopes, and Tina Thompson would become the core pieces of the Houston Comets dynasty.
The NBA draft is an annual event dating back to 1947 in which the (now thirty) teams from the National Basketball Association (NBA) can draft players who are eligible and wish to join the league.
 These are typically college basketball players, but international players are also eligible to be drafted.
 College players who have finished their four-year college eligibility are automatically eligible for selection, while the underclassmen have to declare their eligibility and give up their remaining college eligibility.
 International players who are at least 23 years old are automatically eligible for selection, while the players younger than 22 have to declare their eligibility.
 Players who are not automatically eligible but have declared their eligibility are often called "early-entrants" or "early-entry candidates".
 The draft usually takes place at the end of June, during the NBA offseason.
 Since 1989, the draft has consisted of two rounds; this is much shorter than the entry drafts of the other major professional sports leagues in the United States and Canada, all of which run at least seven rounds.
 Sixty players are selected in each draft.
 No player may sign with the NBA until he has been eligible for at least one draft.
The "Parade" All-America Boys Basketball Team was an annual selection by "Parade" that nationally honored the top high school boys basketball players in the United States.
 It was part of the "Parade" All-American series that originated with boys basketball before branching to other sports.
 Started by the Sunday magazine in 1957, it had been the longest ongoing selection of high school basketball All-Americans in the country at the time of its final selections in 2015.
 Many of the honorees went on to star as college and professional basketball players.
 As of March 2011, there were 162 "Parade" All-Americans that were playing in the National Basketball Association (NBA).
The 1975 NBA draft was the 29th annual draft of the National Basketball Association (NBA).
 The draft was held on May 29, 1975, before the 1975–76 season.
 In this draft, 18 NBA teams took turns selecting amateur U.S. college basketball players and other eligible players, including international players.
 The first two picks in the draft belonged to the teams that finished last in each conference, with the order determined by a coin flip.
 The Atlanta Hawks, who obtained the New Orleans Jazz first-round pick in a trade, won the coin flip and were awarded the first overall pick, while the Los Angeles Lakers were awarded the second pick.
 The remaining first-round picks and the subsequent rounds were assigned to teams in reverse order of their win–loss record in the previous season.

Darrin Hancock (born November 3, 1971) is a retired American professional basketball player.
 In high school and college he was known for his strong offense, while his quick and agile moves to the basket drew comparisons to the likes of Dominique Wilkins.
 A Parade Magazine and McDonald's All-American standout at Griffin High School (Griffin, GA), Hancock was ranked among the country's best high school basketball players in the late 1980s.
 He played his first two college seasons at Garden City Community College, where he was considered one of the top junior college recruits in the nation before transferring to the University of Kansas.
 There he was the starting small forward on the Kansas Jayhawks' Final Four-bound squad in the 1993 NCAA Men's Division I Basketball Tournament.
 Hancock left college after his junior year to play professional basketball and eventually found success in United States semi-pro basketball leagues after several uneventful stints in the NBA.
 He is considered to be among the best all-time Georgia high school basketball players in the state's history.
