Hard Knocks reveals fascinating insights about the Steelers, from leadership moments to Mike Tomlin’s surprising snack preference.

For the first time, the Pittsburgh Steelers will be featured on HBO's "Hard Knocks" series along with the rest of the AFC North. While fans will certainly get a unique look at each team, there's one element of the Steelers' work week that likely won't be captured on camera.

HBO will be debuting a very special in-season edition of Hard Knocks on Tuesday — “Hard Knocks: In Season with the AFC North” — featuring the Pittsburgh Steelers, Baltimore Ravens, Cincinnati Bengals and Cleveland Browns.

These Steelers’ dynamic personalities promise captivating moments as fans get a behind-the-scenes look on the AFC North’s Hard Knocks.

Keith Cossrow, a 1993 Mt. Lebanon High School grad who’s vice president and head of content at NFL Films, said getting the Steelers on HBO’s long-running NFL docuseries “Hard Knocks” (9 tonight, HBO and Max) was a matter of finding the right format.
