Instead of the "Mt Rushmore" idea of including the top few figures from each program, who is the top-dog, #1 guy? The tough ones have an all-time best player and a legendary HC. I don't know as well as you all would, but here's some ideas:
Iowa - Kinnick or Fry?
Minny - ?
Wisconsin - Barry Alvarez or Dayne...Ameche?
Illinois - ?
N'Western - has to be Fitzgerald, right? Player and HC, like Spurrier.
Purdue - Brees....Greise? Tiller?
Indiana - Lee Corso! j/k, I have no idea
Michigan - Yost? Fitz? Harmon? Woodson? Bo? I'd go with Schembechler.
MSU - Duffy? Bubba Smith?
OSU - Archie...George....Pace....Woody?
Penn St - JoePa
Rutgers - Schiano?
Maryland - E.J. Henderson? Randy White? Friedgen?
Nebraska - Dr. Tom
