A former NFL executive said teams did not discipline players in "hundreds and hundreds" of domestic violence incidents during his 30 years in the league, and said he now regrets his role in the failure to take action.

"I made a mistake,'' Jerry Angelo told USA TODAY Sports. "I was human. I was part of it. I'm not proud of it.''

Angelo, who was general manager of the Chicago Bears from 2001 to 2011 and has been out of the league since, said his typical approach after learning of a player's involvement in a domestic violence case was to inquire, "OK, is everybody OK? Yeah. How are they doing? Good. And then we'd just move on. We'd move on.''

"We knew it was wrong,'' Angelo said. "…For whatever reason, it just kind of got glossed over. I'm no psychiatrist, so I can't really get into what that part of it is. I'm just telling you how I was. I've got to look at myself first. And I was part of that, but I didn't stand alone.''

Angelo said his perspective changed when the infamous Ray Rice video surfaced, showing the star running back punching his fiancee in the face in an elevator and causing her to lose consciousness. The video triggered outrage over the league's handling of domestic violence. For Angelo, it brought remorse.
