I watch the Ravens every week. I Watch them on the All-22 after the games are over. There is a severe lack of execution by players at every level of the defense. Blitzers hitting the wrong gap, dumb penalties, missed tackles, blown coverages. There are multiple major errors on the field every single week.
Pees has led good defensive units for 2 years straight before this year. He orchestrated an elite pass-rush to help cover for a secondary that was beyond bad. All of a sudden it's his fault that Jimmy Smith isn't the same player? If it's Pees fault that Smith sucks now, it was also Pees that gets credit for his development and emergence as a top CB prior to 2015 right? I think in reality, it's injury related for Smith, but he is playing and unfortunately not playing well at all.
I don't see how anyone can look at the talent the Ravens put on the field and blame the coaching. There is a severe lack in playmaking at every level of the defense.
It starts with the pass-rush, or lack there-of. No one on the DL can generate a consistent pass-rush besides Dumervil, and he can't do it by himself all game/every week. Pees has been forced to blitz at a much higher rate to get any type of pressure on the QB. It doesn't take a rocket scientist to figure out that blitzing puts more strain on players in coverage.
Let's look at the ILBs who are tasked with covering the middle of the field. Can anyone say with a straight face that any LB on the Ravens is good at covering TEs or RBs in man? Are they dynamic in zone coverage? The answer is no. The LBs are a liability in coverage. They all are - Mosley, Smith, Orr, McClellan.
In the secondary it's not much better. Shareece Wright has played like the Ravens best coverage guy, and he has had some major blunders. Jimmy Smith has been bad. There is no denying that at this point. Webb is decent in zone, but he is small and gives up a lot of catches. Will Hill has been very good this year, especially in man coverage on TEs, but he has had lapses in coverage as well just like the TD that he gave up last night to Benjamin.
So how does anyone expect to the defense to be better against the pass? They struggle to create pressure outside of blitzing (which Pees does a lot and does it creatively). The LBs are bad in coverage, and the secondary is mediocre at best.
It doesn't matter the the Ravens are excellent at run defense because no one even tries to run the ball.
In the end it is at the feet of the DC to get his unit to play better. There might be things that he could do differently, but I doubt the outcomes would change in any significant way. I understand the desire to try something different, but the defense lacks talent where it is needed most in today's NFL.
