Just for clarification, Sherman and Lynch don't work for the NFL. They work for Paul Allen and the Seattle Seahawks. If Sherman and Lynch were bad mouthing the Seahawks I could see them being fired. Unless there are specific rules regarding expressing opinions about the league they can't force Allen to do anything. Paul Allen could tell the league and the other owners to go to hell. If you don't think that happens Google Al Davis. We live in a very litigious society, if the league started pressuring owners to blackball players for speaking negatively, at some point they would get sued. That kind of law suit could jeopardize the NFL's anti-trust exemption. They would never take that chance.
