Basically, they're going to steer away from a traditional 3-4 defense, to a more hybrid form of D that relies on mixing and matching, penetration on the line and totally fucking people's shit up:
Although complex and still a work in progress at this point, the Dolphins will rely on more penetration from the interior defensive line than previous years. It will allow the team to benefit from the athleticism of its linemen as much as the bulk.
The key phrase in all of this, though, is interior penetration. That's an aberration from the standard responsibilities of a 3-4 nose tackle, which spends its time clogging up the middle to allow for the linebackers to make the plays.
This, of course, all will fall into the hands of The Matrix himself, coach Mike Nolan. And who knows what kind of mindfuck this dude will unleash upon opposing offenses with the toys Ireland and Parcells are handing him. Don't be shocked if, one day, Odrick, Randy Starks, Phillip Merling, and Kendall Langford all stack up on top of each other and form a human pyramid and then start shooting lasers out of their eyes and blowing people's heads off. Ok, you got me, that's ridiculous. You don't need to go to the trouble of forming a human pyramid just to shoot people's heads off with lasers from your eyes. I can be so silly sometimes!
