Pittsburgh Steelers defensive end Cameron Heyward believes that the club's defense will not change much under new coordinator Keith Butler.

Dick LeBeau stepped down from his role at the AFC North club last season after 13 years as the defensive coordinator, following their exit from the playoffs in the wildcard round.

Butler was promoted from his role as the linebackers coach to fill the void, and Heyward believes that the internal move will see the Steelers stick to similar principals on defense.

"I don't think there are going to be too many changes," Heyward told the club's official website.

"It's going to be the same details. We will have a couple of new wrinkles, but we won't share them now."

Heyward recorded 53 tackles and 7.5 sacks for the Steelers last season.
