Grading Steelers GM Omar Khan for his first two NFL draft, free agent classes. Do his moves hold up?

On the Wednesday episode of the North Shore Drive podcast, presented by Edgar Snyder & Associates, host Christopher Carter welcomes Post-Gazette Steelers insider Ray Fittipaldo to grade GM Omar Khan on his first two seasons of NFL draft picks and free agency signings. How much credit does he deserve for adding contributors including Joey Porter Jr., Zach Frazier, Keeanu Benton, Payton Wilson and Nick Herbig. Can first-round picks Broderick Jones and Troy Fautanu still emerge as difference makers? And do the draft classes rely on them to be considered successes? On the free agency and trade front, how should we view moves for names including Russell Wilson, Justin Fields, Patrick Queen, Donte Jackson, Larry Ogunjobi, Patrick Peterson, Elandon Roberts, Isaac Seumalo, DeShon Elliott, Van Jefferson and others? Did Khan hit on enough of those guys? Or did the additions end up leaving too much to be desired? Our duo tackles those questions, then ponders how much help the offensive line may still need despite heavy investment in it the past couple of offseasons.
