Goodell wasted an opportunity to stand up for his country. He confirmed he could care less about his product becoming offensive to a large number of fans.
He should resign and be the road manager for the Dixie Chicks.
I speculate that from Goodell's perspective he doesn't want the NFL associated with the United States. He wants to expand the league into Europe. So he is willing to take a hit on US revenues if it means he can present the league as more Globally acceptable.
