Arriving 17 minutes late to the podium, Goodell began by reiterating that his initial response to the Rice case was wrong. “I am not satisfied with the way we handled it,” he said. “I made a mistake. I am not satisfied with the process we went through. I am not satisfied with the conclusion.”

Despite a growing number of calls from women’s groups, advocates for victims of domestic violence and even former players, Goodell said that he had not considered resigning.

“I have not,” he said, adding later that the league’s owners supported him. “I am focused on doing my job, and doing it to the best of my abilities. I understand when people are critical of your performance, but we have a lot of work to do. That’s my focus.”

Hours after Goodell finished speaking, ESPN published a lengthy article citing multiple anonymous sources that said the Ravens had pushed for Rice to be treated leniently and that Goodell agreed to their request.

In a statement, the Ravens said, “The ESPN.com ‘Outside the Lines’ article contains numerous errors, inaccuracies, false assumptions and, perhaps, misunderstandings.” The team added it would fully address the article after returning from Cleveland, where it is set to face the Browns on Sunday.

At the news conference, Goodell did not deviate from comments he made after the scandal broke nearly two weeks ago. Goodell repeated that he had not seen the video of Rice punching Janay Palmer, who is now Rice’s wife, and he was confident that no one at the N.F.L. had seen it either, despite news reports to the contrary. Goodell said he suspended Rice indefinitely last week because the video was “inconsistent” with what Rice had told him about the episode in a meeting before the original suspension.
