Cardiac Hill has more on Lindsey, who's the headliner here, due to his local ties. Cardiac Hill expected him to be taken somewhere between the fourth and sixth rounds, and that might be a bit optimistic, but the Steelers might still be getting a little more value there than with the typical undrafted free agent. The Steelers had four seventh-round picks, however, so these guys are probably all fairly far down their list of priorities. The Steelers had a ton of undrafted free agents last season, but none of them played a huge role with last year's team.
