It has been discussed internally within the Players Union for quite some time. They have a petition signed by hundreds of players willing to Decertify if necessary. Not sure how much its been played out in the media, but I've heard it been discussed as option from a pretty early point in the game. Whether thats just a bargaining chip, a "bluff" if you will, who knows, but they are willing to do it. Or at least the Petition thing says they are. I agree it nots their best option, but it certainly is an option unfortunately. I can't imagine the ramifications of that move though ... would be huuuge as you said.
