Rutgers, Maryland, Penn State, Ohio State, Michigan, Michigan State, Indiana
Purdue, Northwestern, Illinois, Wisconsin, Minnesota, Iowa, Nebraska
I guess with Penn State getting hammered the divisions are fairly equal.
Will go into effect in 2016 when the conference goes to a 9 game schedule. The only protected game is Purdue v. Indiana, who will play every year. Otherwise there will be no protections and the 3 teams from the other division you play will rotate.
