Awesome! Keep winning.
Seriously though, Iowa should NOT be ranked. I don't care that they are 5-0. Look at who they have played:
* UNC-Wilmington: 3-4
* Nebraska-Omaha: 3-3
* MD-Eastern Shore: 2-2
* Abilene Christian: 2-5
* Pennsylvania: 1-3
Combined opponent record = 11-17. 4 of those wins from Iowa's opponents were against non-D1 schools too. 0 of those wins were against any major conferences, and only one win was against an OK mid major conference. That was Nebraska-Omaha beating Northern Illinois, who is 2-3 themselves.
Sure, Iowa COULD be good this year, but the rankings are based off of what's been done as of now. I don't think the above resume screams top 25.
