The Steelers signed Justin Fields as a backup quarterback to Russell Wilson.
Fields' potential as a starter is overshadowed by Wilson's expected role as the Week 1 starter.
The Steelers are taking a low-risk approach with both quarterbacks, allowing Fields to develop while Wilson leads the team.
Fields' fit in offenses is limited, resulting in fewer suitors for the Bears' quarterback.
The Steelers will address areas of improvement, such as the offensive line and wide receiver positions.
