The Denver Broncos defense have had some down moments on the season, but they tend to recover, and go back to playing as the best defense in the NFL. Their visit to the Black Hole to take on the Oakland Raiders was no different.
They had their struggles, especially early, with dumb lack-of-discipline penalties. They also had some issues in coverage—not with everyone, but primarily with their linebackers and safeties. They still ended up playing a really good game, but there has been room for improvement, and there always will be. The biggest priority must be to cut back on the penalties.
