1. All 4 quarterbacks are able to routinely make plays outside of the pocket. They all can run if they get flushed and they all have great pocket presence.
2. All 4 teams have skill position players that can and will beat 1 on 1 matchups. The play callers then exploit those matchups and when they get the matchup they want that is where the ball is going to go.
3. All 4 teams have complete offenses that are able to counter anything the defense shows them. They all can can beat you at all 3 levels and have the ability to be explosive in any of them.
4. Because of what I said in 1-3, all of the defenses are then forced to go out of their comfort zone, get spread out and play a lot of man coverage, often times with only 1 or zero safety help.
5. All 4 teams had very good offensive line play.
With respect to Iowa:
1. When we have had anything that resembles a dynamic QB, we have been very good. Banks, Tate, and CJ. Cade has shown he can do it.
2. We don't have anyone remotely resembling an edge receiver like those 4 teams have. There is nobody on the roster now that be that.
3. It has been painful the last 2 years to watch an offense so incapable of doing anything about what the defense are doing. There has been zero downfield threat, a terrible offensive line, and an immobile QB thus allowing defenses to all play us the same way: no blitz, some sort of man underneath coverage with some combination of zone coverage over the top. We know it and can't do a thing about it.
4. Defenses have dictated to us how we will play offense, not the other way around.
5. Our offensive line play has been less than poor. And that is being nice.
