1. Paterno probably had the most overall losses to sheer longevity. I can't think of any unsuccessful coaches that lasted anywhere close to that long. Ferentz hasn't been around long enough to have more losses.
2. Hayes, Tressel*, Cooper
3. Top 5 for each school? For Michigan I believe it's Chad Henne, John Navarre, Elvis Grbac, Jim Harbaugh, and then maybe either Denard Robinson or Devin Gardner.
5. Ron Dayne, Anthony Davis, Mike Hart, Anthony Thompson
6. I'll say Anthony Davis for Wisconsin.
7. Braylon Edwards, Anthony Carter, Amani Toomer, Marquise Walker, and Jason Avant maybe.
8. (Blanking on their names, but I think they all played in the Tiller era)
10. Penn State
