But that is why Goodell's actions will ultimately be self defeating. In a normal environment (say Tagliabue or Rozelle), the NFLPA might be more inclined to believe it is not precedent setting to have an interview under these circumstances.
But Roger is maximizing every chance he has to rule against players. I have no doubt that if they refused to be interviewed, it would not be a Favre non-cooperation fine or a Brady-like 4 game sentence. They would be gone until Roger is satisfied. And what satisfied Roger is not written down anywhere. It exists in the press reception of news and the opinions of his owners.
