The Denver Broncos are known for having one of the best defenses in the league, but even in victory, Vance Joseph wasn't happy with their performance against the Oakland Raiders. Derek Carr completed 29 for 32 passes for 288 yards and one touchdown in the Broncos' 20-19 win in the final seconds.

That concerned Joseph, who thinks Denver was too conservative on the defensive end at the beginning of the game.

“I thought yesterday defensively that we didn’t play aggressively enough in the first half, and that’s on me,” Joseph said Monday via Arnie Stapleton of The Associated Press. “This offense obviously poses problems because they come in with a lot of different weapons, a lot of different matchup issues.

“So, we played way too cautious. Our defense is based on rushing five, playing press-man coverage. And in the first half we didn’t do that. And it showed, we were really non-aggressive and they took advantage of us. In the second half, we got more aggressive and it showed and we played better. But that’s on me.”

While the Broncos were still able to come away with a victory, Joseph is still concerned Carr was able to complete so many passes. Joseph seems to be putting the blame on himself for the conservative game, so expect to see a more aggressive defensive showing in Week 3 against Joe Flacco and the Baltimore Ravens.
