Team president Bryan Colangelo said he reached a deal with a team he declined to name to trade Okafor last season until it fell apart at the last minute. That led to an awkward situation where Okafor didn’t even travel with the team during the trade deadline. Okafor led the Sixers in scoring as a rookie with Embiid out with injuries. Okafor played 55 games last season and never really meshed with the franchise center. Okafor started piling up DNP-CDs and those stretched into this season, where the Sixers will chase a playoff berth without him.
