Wow..."the shove" is going to get all the press, but IMO the real story is the second, less showy anecdote. Read it, if you haven't yet.
It's a tale of an established, explicit set of NFL rules and systems for rewards and punishments, and how everybody understood it and based their behavior based on it. And then Roger Goodell decided he could just ignore the rules altogether and -- after the fact -- make up an extra-special new punishment for somebody HE personally wanted to see extra-special punished.
That's what we call "a pattern of behavior," kids.
