If accurate, this top 100 list speaks volumes: Linky. Teams ranked 51-100 are the first entry. You'll have to scroll down a bit to see Teams 1-50 and where the good guys rank. Interesting stats. Per the author, the numbers are taken from Department of Education data.
A couple things surprised me. Marquette is at No. 11 and they field no FBS football team. A lot of $$ spent recruiting basketballers Kansas is higher than I would have guessed based on football performance. Similar feeling for Duke. I figured OU would lead thee Big 12 as they seem to offer everyone and bring a lot of folks in.
