Steelers NFL mock drafts: Graham Barton soars in popularity? Blake Fisher a serious Day 2 OT option?

On their weekly Steelers NFL mock draft tracker video, host Adam Bittner and Post-Gazette insider Ray Fittipaldo react to the week in projected selections for the team from around the Internet. Why is Duke's Graham Barton becoming a very trendy pick, notably for ESPN analyst Mel Kiper Jr.? Is he really in the conversation of best center available with Oregon's Jackson Powers-Johnson? Is Notre Dame's Blake Fisher a Day 2 tackle option who could both represent an upgrade over Dan Moore Jr. and give GM Omar Khan more flexibility with his first-round pick? And how plug-and-play ready is Georgia's Sedrick Van Pran-Granger?

Our duo tackles those question along the offensive line, then gets into some other positions. Are the Steelers better off attempting to draft a No. 2 receiver? Or trading for a veteran like Brandon Aiyuk, Deebo Samuel or Justin Jefferson? Is Washington's Jalen McMillarn -- Kiper's pick for the Steelers in the second round -- a good option at No. 51? What about Georgia's Ladd McConkey? Could there be a fit with the Steelers for Pitt's M.J. Devonshire? And is Florida State Jordan Travis a solid options as a development QB behind Russell Wilson and Justin Fields?
