Quote:What Seattle/Atlanta/Jax all run is essentially a base 4-3 under defense

 

What I mean by a basic 4-3 is simply a base 4-3. Four down linemen all playing one gap tech. I'll admit though, that the personnel of the front seven is so all over the place that Jacksonville is pretty much locked in on what Bradley wants to do. Fowler is a prototypical LEO/3-4 OLB but Marks is a penetrative 4-3 DT.

 

Seattle, on the other hand, makes it work because Chancellor destroys just about any back that tries to cut to the outside, and Jacksonville doesn't have Chancellor. Maybe Seattle wouldn't benefit from it more than what they have, but it's quite clear that Seattle's defensive scheme is tailored to its personnel, and not vice versa unlike Jacksonville and Atlanta, who are failing miserably at replicating it.
