My general rule is that if there is no way I can rationally envision the unranked team winning, it's a mismatch, and I cannot in any way imagine IU managing to pull that one off, or stay within 17 for that matter. I dont see this being close either. Iowa was pickign IU defense apart through the air. OSU shouldnt have a problem there. IU Qb was 19 25 255 and 3tds. He aint gonna do that against OSU's passing defense, that is OSU's strength on D.
