Should Fields be QB1?

Will Russell Wilson be good enough to practice this week? What will Mike Tomlin say tomorrow and how will he handle the QB situation? How is this benefitting Justin Fields? Did Fields do enough already for you to name him QB1? The guys noted how Tomlin handled the tackle situation and how it could translate here. What is the early outlook for Indy on Sunday? If Fields works out, where would that trade rank for the Steelers all-time?
