"You didn't pay Cam that money to be a two-gapper. He's a penetrator. That's what he does. That's what he's good at," Clark said. "You have to get pressure if you're going to play cover-2. You drafted Bud (Dupree). You have Jarvis (Jones). You have those guys. Those guys have to be able to rush the passer, and I think what's going to make this team still good is if they can perfect cover-2 to a point to where it's something they can play throughout the game. Now, unless you run your fire zones, unless you run your (cover)-3, the things this defense is known for doing, with it being a young group you're not having to re-teach people. You don't have to re-teach Troy and say, 'Hey, Troy, I need you to learn to play cover-2.' Mike Mitchell comes from a place where they played cover-2 because they had great backers. You look at what should be all first-round draft picks in James Harrison, Bud, Jarvis, (Ryan) Shazier, (Lawrence) Timmons at linebacker, now you've got to count on these guys to be able to drop, to be able to run, and so I think they have the personnel to do it. Coach Tomlin is putting his imprint, his stamp, on this."
The Steelers used a four-man front close to 50 percent of the time last season, but it's likely they want to use more of that nickel front this season. But Clark cautioned against calling the Steelers a 4-3 team at this point.
"They don't have 4-3, all-game personnel yet," he said. "If you draft a Jarvis Jones, and you draft a Bud Dupree, you draft them both to play all the time. You go 4-3 on first downs, now one of those guys is out of the game. You don't draft those guys to watch. So I don't think it goes totally 4-3, but if one of those guys can play hand up, off the ball, or one of them is good enough to play the end and be stout, then it can move that way."
