Sixers president Chris Heck said the team only sold 3,500 season tickets in the 2013-14 season, “and the majority of the holders were brokers,” he said in an interview. The Sixers finished 17th on ESPN’s NBA attendance ranking that season and dropped to 30th in the 2015 season. The average ticket price was roughly $95, compared with an average ticket price across the league that season of $144, according to data provided to CNBC by Ticketmaster.
