Many can point to Colbert for sure, but Tomlin has been more involved in the last 2 drafts with Khan.
The results have been pretty bad so far.
I would disagree that the last 2 drafts have been bad.
2023: Broderick Jones, JPJ, Keeanu Benton, Darnell Washington, Nick Herbig, Cory Trice, Spencer Anderson
2024: Troy Fautanu, Zach Frazier, Roman Wilson, Payton Wilson, Mason McCormick, Logan Lee, Ryan Watts
All of these players are still on the team, that's pretty rare for the Steelers. Lots of Colbert drafts had 5-7 round players getting cut in training camp. Fautanu, Roman Wilson, Logan Lee, and Ryan Watts all hit IR this year, so they remain TBD. Last year Trice missed the full year, so this was basically his rookie season (and he played like a rookie).
JPJ, Benton, Herbig, and Frazier have been awesome.
Darnell, Payton Wilson, and McCormick have played great at times and the two rookies played like rookies at times. I think Darnell is underused by our scheme (not a drafting issue).
Spencer Anderson took over for Moore at times this season and IMO played way better. He's a sleeper for OT next season, but don't know his upside yet.
Broderick Jones is the big question mark and obviously the biggest investment as a 1st rounder. I think the team moving him around all the time and playing him out of position at RT has been the biggest issue to his development. They need to stick him at LT and keep him there no matter what (and improve his OL coach). I fear he'll be another OL player to leave and play much better at another team.
IMO the issues most of these players have had is coaching, not talent. Or staying healthy, which is largely luck.
