Yes and no.
Given the tempo of Iowa's O ... a REALLY effective and efficient passing game might mean just 200 yards per game through the air. I can guarantee you ... if Iowa is able to average 200 yards rushing per game AND 200 yards passing per game ... that implies that our O is clicking on all cylinders. In this scenario ... we're not only winning games ... we're crushing our opponents!
Iowa already has a tendency of playing a field-position style of complementary football that CAN, when it's working, give the O plenty of short-fields. Let's suppose that Iowa can manage to have starting field position that around the 50 yard line several times a game. If Iowa's yardage production is evenly split ... if the Hawks see 4 50 yard fields ... the passing game needs to just rack up 100 yards passing ... and that could be enough for us to chalk up 4 TDs! Then, if they're averaging 200 passing yards per game ... the remaining 100 passing yards is distributed among the remainder of the drives.
However, given that Iowa plays a brand of ball where there aren't always that many more possession ... the remainder of that yardage likely translates to more scores (a few field-goals, let's say). So all of a sudden ... you're looking at an O that is scoring in the ball park of 34+ points per game ... and that's with the opposition having a limited number of times to score themselves.
For Iowa's brand of ball ... an effective passing game is typically an efficient one. Specifically, it's one that enables us to score TDs with good enough frequency whenever we even sniff the redzone.
