Get to know the opponent: Changes to expect from Steelers in 2016

We're taking a look at each of the Bengals' 2016 opponents to get an update on where each team stands heading into the offseason. And, who better to give this update than the fans and bloggers from each team's SB Nation site? First up, we're getting clued in from the Steelers' SB Nation blog, Behind the Steel Curtain, who shared a roundup of the team's additions, subtractions and what to expect from the Bengals' AFC North foe in 2016. The Bengals will get both an early and late look at the Steelers as the teams play in Weeks 2 and 15.

Notable free agent additions: Ladarius Green, TE

Notable free agent departures: Antwon Blake, CB, Brandon Boykin, CB

Trades: None to date

Draft picks expected to contribute as rookies:

Most would assume first round draft pick, cornerback Artie Burns, will be the man to step up, but the hope is he won't be needed in 2016. The picks who are expected to truly make some plays are second round pick Sean Davis, a safety out of Maryland, and Javon Hargraves, a nose tackle from South Carolina State. Both play positions at which the Steelers are extremely thin and could lend themselves to seeing a rookie with notable playing time.

Biggest offseason addition:

No doubt, the biggest addition was bringing in Ladarius Green. With Heath Miller calling it a career, Green will help mask some of the issues which would have been present with Miller no longer in the fold. Green has the size and speed to create mismatches down the middle of the field, something Miller lacked in his later years.

Other than Green, the Steelers' ability to keep their own (LG Ramon Foster, CB William Gay and S Robert Golden) were huge additions this offseason.

Biggest storyline heading into training camp:

The team's secondary will certainly be the most talked about topic heading into training camp, but the team's defense overall should be the biggest storyline. They were able to create turnovers in 2015, but their overall lack of pass defense (30th in the NFL) left the team hanging out to dry on more than one occasion.

Under-the-radar storyline heading into training camp:

For the past two seasons, offensive coordinator Todd Haley has given the offense a goal of averaging 30 points per game. They failed to do so last year, without having Ben Roethlisberger under center for almost six full games. If everyone stays healthy, this could be one of the best offenses in team history, as well as in the NFL in the past decade.

Notable injuries heading into training camp:

Le'Veon Bell's knee injury which ended his 2015 season early will be worth keeping an eye on, as well as an ankle injury which currently has Ladarius Green sidelined until training camp. Other than that, the Steelers have a relatively clean bill of health outside of the usual football maladies.
