1. Iowa
2-3-4. No particular order. Illinois, Wisconsin, Gophs
I thought Wisconsin looked the best overall. They could at least run the ball. In the B1G West that is enough. I think they have a big test next week against a good QB.
Iowa is lost on O and their QB is hobbled. D will always be stingy but they've taken a significant step back on that side of the ball.
Illinois probably played the best team. They pulled one out of the fire. I still think they will have the best OL/DL combo in the West.
Minnesota has the best D in the West. Their O is going to have pull their weight for more than a couple drives and their schedule is brutal.
My ranking would be
1. Wisconsin
2. Minnesota
3. Illionis
4. Iowa
5. Nebraska
6. Purdue
7. NW
