The line is Iowa -3.5 with an O/U of 40. That suggests a final score of 22-18 in favor of the Hawkeyes.
That would require Iowa to kick six FG's and get two safeties. I don't doubt the two safeties but I think that six FG's are way beyond the capability of the Iowa offense.
Maybe the wise guys are thinking eight safeties and two FG's?
