The Week 4 AP Polls came out Sunday afternoon and the Iowa football team was the #18 team, up from #19 the week before.
The other major poll also has Iowa as the #18 team, meaning Iowa did not move at all in the Coaches Poll.
Like Andrew mentioned earlier this month, the College Football Playoff rankings are the only rankings that affect postseason play.
However, it would be naïve to believe that the AP Poll and the Coaches Poll don’t play a part in the perception of college football teams.
