Just looked at the current rankings of opponents for Iowa and ISU. Looking at the AP poll including the other votes, here is the rankings of opponents:
ISU:
2 TCU
3 Baylor
10 OU
21 OSU
22 UI
24 Toledo
34 WV
35 TT
37 KSU
Worthless teams ISU played include UNI, KU, and UT
Iowa:
13 NW
Worthless teams Iowa has played the remainder of their schedule.
Even if Iowa went 13-0, you could make a serious argument that they should not get into the playoffs, because their schedule is absolutely pathetic.
