Najee Harris and Pat Freiermuth were anticipated to be foundational to the Steelers' offense, but after four seasons, the duo is poised to part ways.

They also have quarterback uncertainty, but Freiermuth believes the young core is up to the task of returning the Steelers to a standard they've fallen short of.
