<P0-S0> Shaun Patrick Livingston (born September 11, 1985) is an American professional basketball player for the Golden State Warriors of the National Basketball Association (NBA). <P0-S1>  Livingston entered the league directly out of high school after he was selected in the first round of the 2004 NBA draft by the Los Angeles Clippers with the 4th overall pick. <P0-S2>  In 2007, Livingston suffered a debilitating knee injury that damaged almost every part of his left knee, and it took him about a year and a half to return to action. <P0-S3>  Livingston later played for the Miami Heat, Oklahoma City Thunder, Washington Wizards, Charlotte Bobcats, Milwaukee Bucks, Cleveland Cavaliers, and Brooklyn Nets. <P0-S4>  He has also spent time with the Tulsa 66ers of the NBA Development League. <P0-S5>  He is a two-time NBA champion, winning both with Golden State in 2015 and 2017. <SEP> <P1-S0> The 1980 NBA draft was the 34th annual draft of the National Basketball Association (NBA). <P1-S1>  The draft was held on June 10, 1980, before the 1980–81 season. <P1-S2>  In this draft, 23 NBA teams took turns selecting amateur U.S. college basketball players and other eligible players, including international players. <P1-S3>  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. <P1-S4>  The Boston Celtics, who obtained the Detroit Pistons' first-round pick in a trade, won the coin flip and were awarded the first overall pick, while the Utah Jazz were awarded the second pick. <P1-S5>  The Celtics then traded the first pick to the Golden State Warriors before the draft. <P1-S6>  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. <P1-S7>  An expansion franchise, the Dallas Mavericks, took part in the NBA Draft for the first time and were assigned the eleventh pick in each round. <P1-S8>  A player who had finished his four-year college eligibility was automatically eligible for selection. <P1-S9>  Before the draft, five college underclassmen announced that they would leave college early and would be eligible for selection. <P1-S10>  The draft consisted of 10 rounds comprising the selection of 214 players. <P1-S11>  This draft has the distinction of being the first NBA Draft to be televised. <SEP> <P2-S0> The 2016–17 Oklahoma City Thunder season was the 9th season of the franchise in Oklahoma City and the 51st in the National Basketball Association (NBA). <P2-S1>  On the 4th of July, Kevin Durant announced he would leave the Thunder and sign with the Golden State Warriors. <P2-S2>  On the April 9, Russell Westbrook broke the record of Oscar Robertson of most triple-doubles in a season with 42. <P2-S3>  Westbrook would go on to be named the League's MVP in June. <SEP> <P3-S0> Kevin Wayne Durant (born September 29, 1988) is an American professional basketball player for the Golden State Warriors of the National Basketball Association (NBA). <P3-S1>  He has won an NBA championship, an NBA Most Valuable Player Award, the Bill Russell NBA Finals Most Valuable Player Award, the NBA All-Star Game Most Valuable Player Award, four NBA scoring titles, the NBA Rookie of the Year Award, and two Olympic gold medals. <P3-S2>  Durant has also been selected to seven All-NBA teams and eight NBA All-Star teams.
