Stop us if you've heard this one before. We are worried about the Pittsburgh Steelers offense this season. Despite multiple additions this offseason including an all-new quarterback room and multiple new offensive linemen, this group is still filled with uncertainty heading into the first game of the regular season.

In ranking the offensive positional units, we didn't take into consideration any temporary injuries. Guys like wide receiver Roman Wilson and offensive tackle Troy Fautanu figure into this as healthy because both guys will be back.

Running back

The tandem of Najee Harris and Jaylen Warren is as good as it gets in the AFC. Both guys have a chance to rush for over 1,000 yards this season.

TIght end

The Steelers have a three-headed monster at tight end with Pat Freiermuth, Darnell Washington and Connor Williams are all unique talents but we aren't sure if they will get a chance to show it.

Interior offensive line

This group got a nice bump with rookie Zach Frazier was named starting center to go with guards Isaac Seumalo and James Daniels.

Quarterback

We hope as the season goes on, the tandem of Russell Wilson and Justin Fields climbs this list as we see some production in the passing game.

Offensive tackle

We keep this group above wide receiver because once Troy Fautanu is back, this group gets much better.

Wide receiver

It's hard to find more than two or three wide receiver units in the entire NFL as bad as this group has the potential to be. We expect George Pickens to do all he can but he really has very little help around him.
