Respectfully I disagree. ISU Rutgers and Nevada all unranked aren't good enough wins to justify jumping that high coming from being unranked like we are. My guess if that happens is we could hop to 16-20. I mean there's a chance Iowa isn't rated when we go into that game. Now I doubt it I think we'll crack the top 25 with 4 wins but not by much. To jump much higher would require some others to lose and fall too. It's a big maybe
Iowa jumped from #18 to #7 after 4 weeks last season. Iowa had two top-20 wins in the first 4 (beat #17 Indiana at home, beat #9 ISU on the road). By week 4, there were 8 teams in the top-25 with at least 1 loss.
This year we start at #28, and beating those first 4 teams on the schedule will not impress people. If we stay unbeaten, we will rise due to attrition among the teams ahead of us. I think the 16-20 ranking seems pretty likely.
But we certainly can't just take those first 4 for granted. Aside from Nevada, those other 3 teams are more than capable of pulling the upset. Iowa has been good at handling their business as a favorite over the past 5 years, but we don't play with much margin for error.
