Context paragraphs:
2014 NBA draft: The 2014 NBA draft was held on June 26, 2014, at Barclays Center in Brooklyn.  National Basketball Association (NBA) teams took turns selecting amateur U.S. college basketball players and other eligible players, including international players.  The draft lottery took place on May 20, 2014.  The Cleveland Cavaliers won the draft lottery to earn the first overall pick in the draft; this is the fourth number-one pick for Cleveland since 2003 and third number-one pick over a four-year span from 2011–2014.  This draft would also be the first for the reborn Charlotte Hornets, who played as the Bobcats from 2004–2014, since 2001, when the original Charlotte Hornets last selected as the Charlotte Hornets before moving to New Orleans and eventually becoming the current New Orleans Pelicans.

2015–16 Philadelphia 76ers season: 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.  Jerry would also announce his personal demotion from his original position afterwards.  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.
