Yeah, Ohio has some really good liberal arts schools. I would have thought Xavier would be a national university along the lines of Dayton
I think that Wiscy, Illinois, Ohio State, and Penn State are all very similar and to have 4 B1G clustered that closely together in the late 40s early 50s sounds about right. Nebraska is a total out layer and really fits in with the academics of the Big 12. Notre Dame academically, geographically, and athletically screams B1G.
By the way here are the top 20 (actually 21 as there was a tie at 20) for all BCS Conferences:
6-Stanford
9-Northwestern
10-Duke
15-Notre Dame
15-Vanderbilt
20-UCLA
22-Cal Berkley
22-USC
25-Michigan
27-Wake Forest
28-UVA
29-Georgia Tech
29-UNC
34-Florida
37-Boston College
46-Wisconsin
48-Illinois
48-Texas
50-Georgia
54-Ohio State
54-Syracuse
Conference Breakdown:
