Hinkie resigned, according to Marc Stein, because the hiring of Colangelo, son of 76ers chairman of basketball operations Jerry, was imminent, further limiting his prerogatives.
Sources told ESPN.com that Hinkie, sparked heavily by the Sixers' interest in hiring two-time NBA Executive of the Year Bryan Colangelo to join their front office, decided to leave the organization rather than surrender even more authority than he already has this season.
Adrian Wojnarowski reports that Colangelo's hiring could be announced as early as Thursday.
Hinkie was the architect of "the process," planned losing to get top picks in the Draft, but the losses mounted and two of the top picks in 2014, Joel Embiid and Dario Saric, have yet to play a minute in the NBA. Moreover, rival GMs and agents accused Hinkie of reneging on handshake deals. So, earlier this year, in part because of pressure from the commissioner's office, 76er ownership hired Colangelo's father, Jerry, as chairman of basketball operations. Colangelo became the ultimate decision-maker in the organization.
