New Philadelphia 76ers CEO Scott O'Neil knows he faces a challenge. The team lost much of the fan enthusiasm it established during a 2012 playoff run with a series of poor personnel moves last season. Attendance was down. There is little buzz from the media and sports talk radio. It has no superstar to market. It currently has no coach. And it just traded its best player, all-star guard Jrue Holiday, in a move that commits the team to a rebuilding plan that could last for several years while newly acquired young talent gains experience.
