On their weekly NFL mock draft tracker podcast, host Adam Bittner and Post-Gazette Steelers insider Ray Fittipaldo recap the week in projected picks for the team from around the Internet. -Do coach Mike Tomlin and GM Omar Khan have more needs than they can fill with this class, after trading their second-round pick for DK Metcalf earlier this month? -Why is Tyler Shough emerging as a serious option for the Steelers to slot in behind Mason Rudolph and -- possibly -- Aaron Rodgers? -How seriously should we take coach Mike Tomlin's pro day dinner with Ohio State standouts Will Howard, Quinshon Judkins and TreVeyon Henderson? -Should we play any attention to the growing mock draft momentum toward the Steelers selecting possible Day 1 QB options Jaxson Dart and Shedeur Sanders? -Why is Walter Nolen a divisive figure in the mock daft world and how does he fit with the Steelers' needs compared to defensive tackles like Derrick Harmon and Kenneth Grant? -What are Ray's thoughts about Omarion Hampton and Jahdae Barron, who still consistently show up in Steelers mocks?
