Iowa regularly plays the field position game and that does impair the offensive output. It has been that way for pretty much 20 years, I don't think it's too controversial of a point. Iowa intentionally tries to shorten the game, which leaves the defense on the field for fewer reps and boosts their stats, to the detriment of the offense. It's a good strategy to beat better teams because you'll see games against teams Iowa has no business beating coming down to a possession or two at the end, but the downside is it leaves Iowa susceptible against teams like Northwestern or Purdue last year or Minnesota those years that they totally sucked. I'm sure Iowa could go out there and try to play tempo and boost yardage and even scoring, but the downside of that would be 20 more plays for the defense and it would harm them. Kirk coaches the units to be a cohesive team, which is becoming rare. A lot of teams in Big 12 and Pac 12 just go tempo all the time and it makes their defenses look like hot garbage.
