Is that they can get off the field on their own power. They don't need the offense to ball control or anything like that. When they're up they go get a three 'n out or make it a short possession by getting the stop. When they go back out there again due to offensive incompetence they tend to get that stop too.
This defense is definitely doing that. I keep expecting them to dip but it's pretty clear that we have a top unit and that's a very exciting development that may allow us to make a deep playoff run this year.
