The point is that it has to do with disclosing you've been picked before the league has decided to make a formal announcement, plus keeping communications regarding same confidential. If we have been silenced by an NDA, we'd have to already be in. Nobody else seems to be, except possibly Cincinnati. The rest seem to be going about all of their public politicking just fine, and at least the serious candidates or perhaps all of them may have signed NDAs. It hasn't stopped anybody from making public pronouncements about their respective candidacies.
