Probably the same reason that you had this in your rankings:
6. Minnesota 5-3, 2-3 in BT
7. Iowa
8. Purdue 5-3, 3-2 in BT, with H2H win @ Minnesota
Overall record of opponents:
Minnesota: 29-35
Purdue: 35-30
Agreed. That middle group is just tough to rank. Everyone here agrees that the top four are tOSU, M, PSU, and IL (there is disagreement on the order but everybody has those as the top-4). Also, all but one of us (@FearlessF ) have MSU, UNL, RU, IU, and NU as the bottom five and the one exception has MSU 9th and Iowa 10th.
That leaves five teams to rank between #5 and #9. Here are their B1G games thus far:

As you can see, so far there have only been three games among these five teams:
- Purdue won at Maryland by 2
- Purdue won at Minnesota by 10
- Purdue lost at Wisconsin by 11
Thus, in games among the five:
- 1-0 Wisconsin beat PU at home.
- 2-1 Purdue beat UMD and MN on the road and lost on the road to UW
- 0-0 Iowa has yet to play any of the other four
- 0-1 Maryland lost at home to PU
- 0-1 Minnesota lost at home to PU
Wisconsin has the best percentage but you have to give Purdue some credit for the fact that all three games were on the road for them.
In games against the top-4 these teams are 0-9. I would rank their performances against the top-4 as follows:
- 0-1 Maryland: Their loss was both close and on the road.
- 0-1 Purdue: Their loss was close but at home.
- 0-3 Iowa: Two of their three losses were reasonably close and they are the only team in this group to have played both of the top-2.
- 0-2 Minnesota: A blowout and a two-score loss.
- 0-2 Wisconsin: Two blowouts. Also, I'd be more willing to say "well yeah that happens against great teams" if it was tOSU and M rather than tOSU and IL.
In games against the bottom-5 these teams are 9-1. I would rank their performances against the bottom-5 as follows:
- 2-0 Minnesota: Two blowouts.
- 2-0 Iowa: Two near-blowouts.
- 1-0 Purdue: A too-close win over UNL.
- 3-0 Maryland: Three wins is good but two close calls and a two-TD home win over MSU are not impressive.
- 1-1 Wisconsin: These teams shouldn't be losing to the bottom-5. The blowout of Northwestern is good but the loss is bad.
Like I said upthread, all five of these teams have results that make it look like they are at least as good as #4 Illinois and results that make it look like they are no better than the best of the bottom-5. It will work itself out. There are five games among these five teams over the final four weeks of the season:
- Maryland at Wisconsin on 11/5 noon, BTN
- Iowa at Purdue on 11/5 noon, FS1
- Wisconsin at Iowa on 11/12 TBD
- Iowa at Minnesota on 11/19 TBD
- Minnesota at Wisconsin on 11/26 TBD
