The Buckeyes first 3 road opponents have all resided in the state of Indiana, and have all lost. 

Week 1 against IU, 23-3, Week 4 against Notre Dame, 17-14, Week 7 against Purdue 41-7.

I wonder when the last time a team has won 3 games in the same state, that wasn't their home state. Buckeyes could make it 4 if they can make it to and win the Big 10 title game.
