My first pass guess:
1. Wisconsin - 8-1 / Loss at Penn St.
2. Iowa - 7-2 / Losses to WIS at home and at PSU
3. NW - 5-4 / Losses to MICH, at MSU, WIS, at Iowa
4. PUR - 4-5 / Losses at NEB, OSU, at MSU, Iowa, WIS
5. NEB - 3-6 / Losses at MICH, at WIS, at NW, at OSU, MSU, at Iowa
6. MINN - 3-6 / Losses to Iowa, at OSU, at NEB, PUR, NW, at WIS
7. Illinois - 0-9 / Losses to everyone
Iowa's Big 10 opener vs. Wisconsin will be a huge game.
If Iowa pulls out a W vs. WIS, they have a very realistic shot at getting to Indy.
WIS has a pretty brutal road schedule as they travel to Iowa, MICH, NW, PSU and PUR.
