Sometimes I get disinterested in posting but I usually read the board regularly. I haven't seen many posts that describe details of Swartz's scheme. But there is information out there that should provide insight. Some of these articles are long so I won't post them in their entirety. I'll just give the link. They are really worth reading.

One thing I will say is that Swartz's scheme is based on pressuring the QB not stopping the run. This can't be disputed because it comes directly from his own mouth. Run stopping is a by-product of his scheme, not the aim.
Jim Swartz doesn't care about being #1 aginst the run.

Swartz does put a priority on the D line at the core of his scheme.
Getting pressure without blitzing

More D line emphasis with D5 front. He will mix in a 5-D linemen front in certain situations.
Saw it in Philly, it's coming to the Browns.

Expect a lot more man and a lot less zone coverage. ( I think this is sprinkled into several of the above articles.)

IMO, the LBs we have now will be fine in this defense.

To execute this properly we're going to need 9-10 DL
