So says FiveThirtyEight.com:

As if losing to the Buckeyes wasn’t enough, Penn State fans now need to keep a close eye on every Ohio State game from here out. Because the teams share a division and because OSU now holds a head-to-head tiebreaker over Penn State, Ohio State will need to lose twice in conference play to give PSU a shot at winning the East. That’s not very likely; our model gives Ohio State a 44 percent chance of winning every remaining regular-season game, much less winning at least three of four. But OSU’s best chances to lose will come in its games at Iowa this weekend and at Michigan on Nov. 25, so those are also Penn State’s highest-leverage games left in the season (aside from the Lions’ own matchup against Michigan State on Saturday).
