"The biggest thing is that you have two uncovered linemen right in there with the nose tackle, and so the nose tackle can move a lot of different ways. It gives you an extra athlete on the field. If you don’t get a lot of looks at it, you have to make a lot of decisions, and learn a lot of things in a short period of time. You don’t have the continuity of what you played last week and the week before, and now you play that this week. The big thing is, it’s a great run defense. That makes a big difference."’
