If Russ can't lead the Steelers to a Super Bowl this year, Fields should be the choice at QB

Can the Steelers win the Super Bowl if Russ played to last year's ability? If not, then it should be Fields this year, even if he has some bad games. Fields seemingly has moved past the version who had atrocious games. The Steelers WRs are not getting separation, and Fields is still making it work. Don't dismiss the Steelers coaching staff's impact.
