It won't take more than a day to happen but thousands of professional reporters will defend ESPN's prerogative to tell its staff to shut up about Goodell already. There will be reasons. It's Olbermann so some of those reasons will be based in reality. They will also be irrelevant.
The bottom line is this. If the network exists to promote the multi-billion dollar professional athletics industry rather than.. you know.. report on it, then the people who work for that network aren't doing journalism. They are doing PR.
