I think the relative difference between the two divisions is overstated once you set OSU aside. They have been the clear class of the East for years now. This year, Michigan is probably the clear #2, with there not really being a ton of difference between Wisconsin, Michigan State, Iowa, Purdue, Minnesota and PSU. Nebraska has shown they can play with anyone and Illinois is better than the bottom of the East and Northwestern is better than Rutgers and Indiana. If I was going to rank them top to bottom:There have been numerous posts about how bad the B10 West is this year. Surprisingly, two of toughest games OSU has played in the B10 this year have been at Minnesota and at Nebraska.
OSU
<insert maybe a mile>
Michigan
<insert maybe a half mile>
Wisconsin
Michigan State
Iowa
Purdue
Minnesota
Penn St.
Illinois
Nebraska
Maryland
Northwestern
Rutgers
Indiana
That would make the East top-heavy with 3 of the top 4, but the West has 4 of the top 7.
