Question: What NBA Finals featured two of the most storied franchises in the NBA who had faced each other six times in the 1960's?
Context: The 1960 NBA World Championship Series was the championship round of the 1960 NBA Playoffs, which concluded the National Basketball Association 1959–60 season.  The best-of-seven series was played between the Western Conference champion St. Louis Hawks and the Eastern Conference champion Boston Celtics.  It was Boston's fourth trip to the NBA Finals and St. Louis' third.  The Celtics beat the Hawks 4–3.  The Finals featured Hall of Famers Bill Russell, Bob Cousy, Tom Heinsohn, Frank Ramsey, Sam Jones, K.C. Jones, Coach Red Auerbach, Bob Pettit, Cliff Hagan, Slater Martin, Clyde Lovellette, and Coach Alex Hannum. The 1998 NBA Finals was the championship round of the 1998 playoffs of the National Basketball Association (NBA) and the conclusion of the 1997–98 NBA season.  The Eastern Conference champion Chicago Bulls played against the Western Conference champion Utah Jazz, with the Jazz holding home-court advantage with the first 2 games in Salt Lake City.  In a repeat of the previous year's Finals, the Bulls won the series 4 games to 2 for their third consecutive NBA title and their sixth in eight seasons.  Michael Jordan was voted the NBA Finals MVP of the series (he also had won the award the last five times the Bulls won the Finals: 1991, 1992, 1993, 1996, and 1997).  This would be his sixth NBA championship and sixth Finals MVP award in six full basketball seasons.  Until 2014, it was the last consecutive Finals rematch between two teams. The Celtics–Lakers rivalry is a National Basketball Association (NBA) rivalry between the Boston Celtics and the Los Angeles Lakers.  Both the Celtics and the Lakers are the two most storied franchises in the NBA, and the rivalry has been called the best in the NBA.  The Boston Celtics and the Los Angeles Lakers have met a record 12 times in the NBA Finals, starting with their first Finals meeting in .  They would both go on to dominate the league in the 1960s and 1980s, facing each other six times in the 1960s, three times in the 1980s, and two times in the late 2000s. The 1987 NBA Finals was the championship round of the National Basketball Association (NBA)'s 1986–87 season, and the culmination of the season's playoffs.  The Western Conference champion Los Angeles Lakers defeated the Eastern Conference and defending NBA champion Boston Celtics 4 games to 2.  The key moment of the series was Magic Johnson's junior sky hook in Game 4.  This was the tenth time that the Celtics and Lakers met in the NBA Finals (more than any other Finals matchup).  It would be the Celtics' last Finals appearance until the two teams met in 2008. The 1978 NBA World Championship Series was the championship round of the National Basketball Association (NBA)'s 1977–78 season, and the culmination of the season's playoffs.  The series featured the Western Conference champion Seattle SuperSonics against the Eastern Conference champion Washington Bullets.  The Bullets defeated the SuperSonics in seven games to win the NBA championship.  Bullets power forward/center Wes Unseld was named MVP of the series.  Before the Cleveland Cavaliers' Game 7 win at Golden State in the 2016 NBA Finals, this was the last time a road team had won Game 7 in the NBA Finals.  The 1978 Finals is the only NBA Finals series since the 1958 NBA Finals in which both teams had under 50 wins.  The 1979 Finals are the only NBA Finals to feature two teams with under 50 wins in an 82-game season. The 2013–14 San Antonio Spurs season was the 47th season of the franchise, their 41st in San Antonio and the 38th in the National Basketball Association (NBA).  They entered the season with an NBA-record ten international players.  This season also marked the first time that the Spurs have made back-to-back Finals appearances, also against the Miami Heat, whom they lost against in last year's NBA Finals in seven games and suffered their first loss in the NBA Finals.  Unlike the previous year, the Spurs avenged their NBA Finals loss and became NBA Champions after defeating Miami in five games, winning their fifth NBA Championship.  The Spurs outscored the Heat in the series by the largest per game average point differential (14.0) in Finals history.  San Antonio's Kawhi Leonard was named the Finals Most Valuable Player (MVP). The Miami Heat are a professional basketball team based in Miami, Florida that competes in the National Basketball Association (NBA).  The Heat were formed in 1988 as an expansion franchise along with the Charlotte Hornets; as of 2017, they are the only new franchise of the past generation to win any NBA titles.  The Heat and the Orlando Magic are the two NBA franchises that are located in the state of Florida.  Since entering the league, Miami has fielded squads that have made the playoffs 19 out of 28 seasons, captured 12 division titles, five conference titles and three NBA Championships.  They defeated the Dallas Mavericks in the 2006 NBA Finals, the Oklahoma City Thunder in the 2012 NBA Finals, and the San Antonio Spurs in the 2013 NBA Finals. The 1959 NBA World Championship Series was the championship series of the 1958–59 National Basketball Association season, and was the conclusion of the 1959 NBA Playoffs.  The best-of-seven series was played between the Western Division champion Minneapolis Lakers and the Eastern Division champion Boston Celtics.  It was Boston's third trip to the NBA Finals and Minneapolis's sixth.  The Boston Celtics swept the Lakers 4–0.  That was the start of the Celtics' 8 consecutive championships, from 1959–1966.  To date, this is the most recent time that an NBA team from Minnesota appeared in an NBA Finals, as well as the first of two times in NBA history that a team with a losing record made the NBA Finals (the other was in 1981). The Lakers–Spurs rivalry is a National Basketball Association (NBA) rivalry between the Los Angeles Lakers and the San Antonio Spurs.  The rivalry started in the late 1970s and peaked in the late 1990s and early 2000s.  Since 1999, the teams have met in the NBA Playoffs 7 times, with the clubs combining to appear in seven straight NBA Finals from 1999–2005.  Additionally, the teams won each NBA Title from 1999–2003 (the Spurs won in 1999 and 2003, while the Lakers won in 2000, 2001, and 2002).  From 1999–2004, the rivalry was considered as the NBA's best, as each time the clubs faced each other in the playoffs, the winner advanced to the NBA Finals.  The rivalry fell off from 2005–07, with the Lakers missing the playoffs in 2005 and losing in the first round to the Phoenix Suns in 2006 and 2007, but intensified again in 2008 when they met in the Western Conference Finals, and later on, again in the first round of the 2013 Western Conference playoffs. The Los Angeles Lakers are an American professional basketball team based in Los Angeles, California.  They play in the Pacific Division of the Western Conference in the National Basketball Association (NBA).  The Lakers' franchise was founded in 1947 in Detroit, Michigan before moving to Minneapolis, Minnesota, where the team got its official title from the state's nickname, "Land of 10,000 Lakes".  The Minneapolis Lakers won five NBA Finals before relocating to Los Angeles in the 1960–61 NBA season, becoming the first West Coast team in league history.  In the 1960s, the Lakers reached the NBA Finals six times, but lost every series to the Boston Celtics, beginning their long and storied rivalry.  In 1972, with future Hall of Famers Wilt Chamberlain, Gail Goodrich, and Jerry West, the Lakers compiled a 33-game winning streak, the longest streak in U.S. professional team sports, and won their sixth title under coach Bill Sharman.  The Lakers' popularity soared in the 1980s when they won five additional championships during a nine-year span with the help of Hall of Famers Magic Johnson, Kareem Abdul-Jabbar, James Worthy and coach Pat Riley, the franchise's all-time leader in both regular season and playoff games coached and wins.  Two of those championships during that span were against their arch-rivals, the Boston Celtics.  With the team of Shaquille O'Neal, Kobe Bryant, Toby Tincher, and Hall of Fame coach Phil Jackson, the Lakers played in four of the first five NBA Finals of the 21st century; winning three consecutively from 2000 to 2002, and losing the fourth in 2004.  The Lakers would then conclude the decade with three straight Finals appearances; losing to the Boston Celtics in 2008 but then prevailing with back-to-back championships against the Orlando Magic in 2009 and the Boston Celtics in 2010.  The 2010 championship marks the 16th NBA championship in Lakers franchise history.
