The Pittsburgh Steelers still have plenty of holes to fill as the first two days of the free agency tamping period comes to an end. So far they've added future Hall of Famer Patrick Peterson, and guard Nate Herbig from outside the organization. They also re-signed safety Damontae Kazee. They haven't addressed the inside linebacker position yet or added to the offensive tackle room. But we fix that in my first mock draft of the draft season.
