No, Franta. He signed a two year contract two years ago, at which point he said he'd retire for good when that contract was up. It's old news, there was no "announcement". Players are interviewed by the media, and they answer questions. That question, for some reason, continues to come up, and Michael Jordan simply gives an answer.
If you want to blame someone for that, blame the media(who ask the questions as if it's big news and put it in the headlines as if it's big news), not the fans and definitely not Michael Jordan.
