While there has been a lot of concern over the Steelers' defense in 2015, Keith Butler apparently has a few surprises in store.
The last time the Patriots played the Steelers, Pittsburgh gave up 51 points on its way to its second straight 8-8 season.
Since then the defense has lost several former leaders but has gotten younger and faster. Going into Thursday night's opening game against New England, Pittsburgh is going to have to find answers against Tom Brady after its defense looked porous throughout most of the preseason.
Part of that solution may come from the Steelers' new defensive coordinator, Keith Butler.
