The 1951 NBA All-Star Game was an exhibition basketball game played on March 2, 1951, at Boston Garden in Boston, Massachusetts, home of the Boston Celtics.
 The game was the first edition of the National Basketball Association (NBA) All-Star Game and was played during the 1950–51 NBA season.
 The idea of holding an All-Star Game was conceived during a meeting between NBA President Maurice Podoloff, NBA publicity director Haskell Cohen and Boston Celtics owner Walter A. Brown.
 At that time, the basketball world had just been stunned by the college basketball point-shaving scandal.
 In order to regain public attention to the league, Cohen suggested the league to host an exhibition game featuring the league's best players, similar to the Major League Baseball's All-Star Game.
 Although most people, including Podoloff, were pessimistic about the idea, Brown remained confident that it would be a success.
 He even offered to host the game and to cover all the expenses or potential losses incurred from the game.
 The Eastern All-Stars team defeated the Western All-Stars team 111–94.
 Boston Celtics' Ed Macauley was named as the first NBA All-Star Game Most Valuable Player Award.
 The game became a success, drawing an attendance of 10,094, much higher than that season's average attendance of 3,500.

 Eleven of those occurred between 1957 and 1969, with a dynasty led by center Bill Russell and coach/general manager Red Auerbach.
 The Celtics won two more titles in the 1970s under coach Tom Heinsohn, and three more in the 1980s under the leadership of forward Larry Bird.

 In a 2009 Yahoo! Sports article Nelson was ranked the third best general manager of the decade after producing nine 50-plus win seasons in a row and the first Finals appearance in franchise history in 2006.
 Nelson assembled the Mavericks team that would later win the 2011 NBA Championship.
The 2015–16 Philadelphia 76ers season was the 77th season of the franchise in the National Basketball Association (NBA).
 It was also the second straight season that Joel Embiid, their third pick in the 2014 NBA draft, would not suit up for the 76ers due to a leg injury.
 Philadelphia broke the record for the longest losing streak in American professional sports history with 27 straight losses over this season and last season with a 114–116 loss to the Houston Rockets.
 The losing streak would reach to 28 games (with the 18 straight losses tying the record for longest opening season losing streak with the 2009–10 New Jersey Nets) before getting their first victory at home against the Los Angeles Lakers, which was also Kobe Bryant's last game against the 76ers in Philadelphia.
 Philadelphia would also hire former Phoenix Suns owner, coach, general manager, and four-time NBA Executive of the Year winner Jerry Colangelo on December 7, 2015 as their Chairman of Basketball Operations.
 Eleven days later, former Denver Nuggets, Phoenix Suns, New York Knicks, and Los Angeles Lakers head coach Mike D'Antoni would join the team as an associate head coach.
 Near the end of the season, general manager Sam Hinkie would announce his resignation from his position, being replaced by Jerry's son Bryan Colangelo before the end of the season.

 They finished just one game shy of tying the NBA record for most losses in a season set by themselves during their 1972–73 season when they went 9–73.
 However, it would be the season where Sam Hinkie's goal of "The Process" came into full fruition since they'd later earn the #1 selection in the 2016 NBA draft.

 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.
