The Los Angeles Chargers' 23-20 loss to the Green Bay Packers on Sunday was their fifth one-score defeat this season.
It also marked another game in which the opposing offense had one of its best outings of the season.
"We just fed up," safety Alohi Gilman said. "Something's got to change."
In a strong response to a reporter asking if he would consider significant changes on defense, Chargers coach Brandon Staley said he wouldn't.
"I have full confidence," Staley said. "Like I've told you from the beginning, I have full confidence in our way of playing. Full confidence in myself as the playcaller, in the way that we teach and the way that we scheme. Full confidence in that. We got to bring this group together and do it consistently. ... And that's where it's at.
"So you can stop asking that question, OK? I'm going to be calling the defenses ... so we're clear. So you don't have to ask that again."
