Minny, Iowa, and Illinois all go down.  After today the B10 will have only 2 undefeated teams (or just 1 if Nebraska loses to 0-2 Fresno State).  The B10 is officially the 5th best conference.  

As mentioned in other forum topics, the Big10's problems are systematic due mainly to population shift.  Although the B10 may never overtake the SEC due to this, it should at least be competitive with the other conferences.  Right now it is not.
