In Week 1, when Brodie Croyle threw two touchdowns and manufactured back-to-back scoring drives in the air, most Ravens fans and players called it a fluke, a sign of the unit’s complacency. Now in Week 2, following Philip Rivers monster 440 yard game, some of that reassuring “it won’t happen again” mentality is fading – and many fans are wondering not if it will happen, but when it will start to affect the Ravens record.

The Ravens secondary play this season should be a big concern for the Ravens and their fans. With the exception of two interceptions against Rivers on Sunday, there has been little to get excited about. The unit has been bounced in every possible way – confused by play action, outrun on deep balls, and out of position on screens and crosses.

Here are four reasons the Ravens secondary has looked so bad – things we all should have seen coming – and how to fix it.

1. Coaching. This is not a lamentation for the days of old and the return of Rex Ryan. Ryan’s secondaries were rarely perfect and often flawed, especially against good receivers and quarterbacks. But Greg Mattison certainly has plenty to work on. Luckily, Mattison has a lot to work with, as well. Mattison and John Harbaugh both noted after the game that some of the Chargers biggest and most damaging plays were the result of missed coverages and defensive confusion. This was most notable on the Darren Sproles swing pass for an 80-yard touchdown; no one accounted for Sproles. No one.

The Ravens run complex schemes, but the first rule of any defense is know your man. Mattison needs to have his entire defense in the film room all week, playbooks open and pens out. Mattison has some work cut out for him, though. Remember, most of the Ravens corners right now are cast-offs from other teams. Foxworth and Washington were both underperforming high round picks that the Ravens targeted for their speed. They are supposed to be a work in progress. The entire Ravens defense has the talent to be very good, but only if they can execute their playbook.

2. Size. Fabian Washington, Domonique Foxworth, Chris Carr, Frank Walker. All fast, all around 5’11 and 175 (some would even argue with pads on). That’s not quite Chris McAlister and  Samari Rolle. The current Ravens corners aren’t especially small, but you won’t find anyone calling them big. These corners won’t have much success chucking receivers at the line or bumping them downfield, which leads to an entirely different style of play for this secondary than most Ravens fans are used to. In their defense, Washington and Foxworth did an impressive job of staying with their coverage throughout the game on Sunday, but they simply weren’t able to make the plays when the ball game.

Is it truly good coverage if you don’t make the play, though? The Ravens corners need to learn how to run with their man and play the ball. In the Chargers later series, we saw some of this happening. Kudos to you, Frank Walker. It needs to happen more. Speed can’t be taught, but finding the ball can be.

3. The Pass Rush. Another familiar complaint from the past few years. If you hit the quarterback, he can’t throw the ball. And if he can’t throw the ball, no one can catch it. And even if you can’t stop him from throwing, maybe you can stop him from throwing it well. The Ravens front-seven needs to do more to help their secondary be effective. The Ravens actually got pretty solid pressure on Rivers on Sunday, but only when bringing the house – and eventually even that stopped working. Without the blitz, the Ravens pass rush looked handicapped against the Chargers, who were missing three (three!) starters on the offensive line. Terrell Suggs was solid throughout most of the game, but always a half-step behind, and only got through on the blitz. We haven’t seen rookie motor Paul Kruger yet because the Ravens can’t find room for him, but it may be time for that to change.

The Ravens need to find ways to get pressure even when rushing three or four. It’s that simple. Haloti Ngata takes up two men all be his lonesome, that leaves 3 or 4 on the line (depending on the alignment) to handle three Ravens rushers. That match-up should favor the defense pretty consistently. Yes, I’m looking at you Trevor Pryce and Terrell Suggs. If the current rushers cannot get it done, let’s try something new. Kruger is known for his motor, which is precisely what the Ravens defensive line needs.

4. Philip Rivers. Yup, I’m going to just plain say it. Part of the Ravens struggle was simply Philip Rivers. Where was Ed Reed? Ed Reed was all over the field. But wherever Reed went, Rivers went the other way. Rivers held this game together for the Chargers. He spotted blitzes and rushes, helping his handicapped offensive line protect him. He got rid of the ball quickly and knew when the rush was coming. And he put the ball high and out of reach of the Ravens defenders time and time again. Rivers is one of the league’s best – perhaps only Manning and Brady are better right now (maybe not even Brady right now) – and he might have the most raw talent of any quarterback out there.

So, how do the Ravens fix this? Well, don’t play good quarterbacks. That won’t work. The Ravens get Big Ben twice, Palmer twice, Manning, Brady, Favre, Cutler once each… Let’s start by just avoiding Philip Rivers. Done. We won’t have to see him until at least week 18.
