I didn’t do reverse-engineered brackets for the 2021 Iowa high school football playoffs this year, for a variety of reasons. However, they exist elsewhere on the Internet.
MaxPreps has brackets and scores in all six classes (now that football has a 5A), and the reduced fields in the larger classes is accurate. However, you do have to go through an ad-blocker warning and an autoplay video box.
The page linked above also has brackets going back to 2010, so it’s possible that all the work I did on reverse-engineering in the years with pods was an unnecessary exercise. Oh well. My version had records and seedings, though.
There’s also a page for state volleyball, but also without records and seedings.
