Running the 46 defense, which the Jets have alluded to running alot, and especially running the Ryan defense in any form, is based on one thing. Pressure. Pressure, pressure, pressure. Coach Ryan’s defense is an aggressive defense, that relies on getting to the quarterback as much as possible. To do this as much as Rex wants to, you don’t need GOOD cornerbacks. You need SHUTDOWN cornerbacks. You don’t get one as good as Darrelle Revis more often than once in a lifetime. With all due respect to Kyle Wilson, he is not as good. Revis takes the number one threat from the other team out of the game, an essential element to the Ryan way.
If you need further proof, take a look at the Dallas Cowboys last season. They were 23rd in the NFL in pass defense. That is what the Ryan defense looks like when you can’t cover anybody. No, the Jets wouldn’t be that far down without Revis, but they certainly won’t be in the top 10 without him.
