I ranked your scenarios in how likely I envision each oneI think if that happens its due to the following factors - and Iowa probably needs at least 2 of them:
3) - they are hot from 3 (at least 10 makes)
2) - they destroy us on the offensive boards (they get at least 45% of their misses)
1) - they shoot a ton of FTs (make at least 20)
Nah) - they don't turn the ball over (<12 TOs)
