Sorry, but do you actually follow the Hawks? Why the hell would total O be the measuring stick for the O, given the style of O we play? We play ball-control, field-position ball ... that, ideally, attempts to be somewhat efficient as it relates to scoring. Furthermore, our offensive style attempts to complement the defense ... by minimizing turnovers ... while the D attempts to exploit errors/turnovers by the opposition. We also play a brand of ball where the special teams are every bit on the same footing as the O and the D ... our special-teams play helps to make the difference in games.
Here are what the numbers look like for scoring O ... which, even then, isn't the best metric ... but certainly it is better than total O!

If you consider when Iowa had some of its worst OLs ... that often correlates most directly to our poorest scoring Os. Most notable being the '07, '12, and the '21 seasons. Also notice that whenever our scoring O is particularly bad one season ... it typically rebounds pretty significantly the following season. To bring you attention to this, hopefully obvious, observation:
'04 to '05: improved 33 spots
'07 to '08: improved 77 spots
'09 to '10: improved 37 spots
'12 to '13: improved 33 spots
'16 to '17: improved 29 spots
'19 to '20: improved 48 spots
Obviously historical precedent guarantees nothing ... the players have to channel their disgust from their play in '21 to BOTH their individual and team development. However, should they improve along the lines of historical precedent ... it's not unreasonable to suppose that the scoring O of the Hawks could jump into the upper 60s (in terms of scoring O ranking).
If we see that improvement on O ... and if the D can continue its high-level of play ... there's plenty of reason to justify why the Hawks sold-out their home slate.
