As we know the committee has all these checks and balances they look at to decide who is in the top four. If Wisconsin wins next week we pretty much know Ohio State gets in because we beat them. But if Penn St wins people are saying they might get in over Ohio State. Here is why the committee won't let that happen. Again it's all about who has more checks according to their criteria.
Better Record: Ohio St
Better strength of schedule: Ohio St
More Wins vs top ranked teams: Ohio St
Head to head: Penn St
Conference Champ: Penn St
Now unless the committee tries to say one of these is weighted more than the others, Ohio State checks more boxes and is in.
