Iowa got absolutely dominated by Purdue, yikes... They still have one of the best wins in the country over Penn State, though they were losing before Clifford's injury. Other wins against Iowa State and Maryland help the depth aspect of Iowa's resume, but the fact that they really beat an injured Penn State instead of a healthy one leaves them below Alabama.
Iowa is 6-1. Only loss it to Purdue. Best wins are over Penn State (5-1) and Iowa State (4-2). This team may be a little overrated in my poll, but I think their resume demands ranking here. They are in trouble if they dont force turnovers. 
The expected Iowa letdown happened.  Their defense wasn't able to play up to their normal elite level and the offense failed to pick up the slack where they were covered by the defense all season.  
#2 BIG10 Team ✔️Facing unranked Purdue ✔️The end was determined before you even started. Here's to figuring out what 'Good QB Play' is.
Iowa was a victim of Purdue's #2 magic. They appear to have a relatively easy schedule and could make it to the conference championship if they don't have more slip ups
