Steelers' defense girding for test against Ezekiel Elliott (The Associated Press)

Cam Heyward knows better than to get ahead of himself. Sure, the Pittsburgh Steelers’ run defense was better last week against Baltimore, when the Ravens needed 29 carries to manage 50 yards. Then again, considering how ineffective it was in losses to Miami and New England – losses Heyward missed due to a hamstring injury – it’s a backhanded compliment at best.
