Steelers practice report: How can Arthur Smith get Najee Harris, running game DOMINATING again?

Post-Gazette Steelers insiders Brian Batko and Ray Fittipaldo report from the team's practice facility ahead of a crucial NFL Week 16 matchup with the AFC North rival Baltimore Ravens. How can OC Arthur Smith get Najee Harris, Jaylen Warren and the running game back on track after an ugly performance last week against the Philadelphia Eagles? Can he get more out of young offensive lineman such as Zach Frazier, Broderick Jones and Mason McCormick? Or does he need to switch up his play calling at tactics? Where does George Pickens' injury situation stand, and what impact could that have on QB Russell Wilson and the passing game? Then on the defensive side of the ball, how important is T.J. Watt's availability to helping DC Teryl Austin stop Ravens QB Lamar Jackson? Can the unit survive with Alex Highsmith and Nick Herbig as the lead pass rushers? Our duo tackles those questions and more.
