Only if you are really, really cynical. If you're not cynical, it reads like this:
He made a decision that he thought was warranted. He realized after the fact that he made a mistake. He admitted that he made a mistake and figured out a way to correct that mistake for the future.
To me, that is the epitome of what being a leader and an upstanding person is all about. And I'm not even remotely a Roger Goodell fan. I think some of the things he's done - worrying more about expanding the season, less about player injuries and concussions in particular - are shameful. But in this case, he deserves some credit, IMO.
I guess I'm cynical by your definition. I prefer leaders think through their decisions first, have a rationale and justification to support it and defend them. Goodell obviously didn't think his decision through on Rice and couldn't defend it when challenged so he came up with new one that was more popular.
I guess we hold our leaders to different standards but I expect them to get it right the first time not wait for popular opinion to sway them. In my opinion, that behavior doesn't represent the actions of a leader, it's the action of a politician.
