It's no secret that the 76ers' Andrew Bynum experiment was a disaster. The acquisition of the 7-foot center in last summer's four-team trade ultimately set the Sixers back several seasons. Bynum who made $16.9 million last year never played for the team because of chronically injured knees. After being urged by WIP-FM (94.1) host Angelo Cataldi new Sixers chief executive officer Scott O'Neil apologized Thursday morning to fans who bought tickets with the hope of seeing Bynum play. "I apologize on behalf of the Sixers to any fan who invested and thought Bynum was going to be their guy and be the savior" O'Neil said. "At the end of the day that's our apology to every fan not just to [Cataldi]. "However we are going to take some chances when we can take some chances. And sometimes they're not going to work. And sometimes they are." He said the Sixers will not talk negatively about players when things fail to work out. Negativity he said will not help the franchise or the fans and it could affect the ability to attract free agents.
