Penn State is reeling from two straight losses, to Ohio State and Michigan State, and puts its No. 18 national ranking and 4-2 record on the line tomorrow against Indiana (4-3)

• BETTING LINE: Penn State minus-15

From the withering late defense against Appalachian State to the three touchdowns called back by penalties against Kent State to the turnovers against Pitt and Illinois to the two uncovered onside kicks, mistakes piled up in wins. Then Penn State made a few against Ohio State and Michigan State (more vs. the latter) and couldn’t compensate with its roster superiority.

All along, coach James Franklin said the game tape showed his team improving week to week. “Did not feel like that this past week,” Franklin said after the 21-17 loss to Michigan State.

Penn State dropped three potential interceptions (two in the fourth quarter) against the Spartans, along with committing a critical personal-foul penalty on a goal-line defensive series and failing to cover a fake punt. The Lions have been sloppier this season than last, and the Michigan State loss brought out the worst in them.

Through six games, the Lions have committed 12 more penalties, fumbled five more times (losing four) and dropped their pass-completion rate by 16 percent. Fundamentally, they’re lagging.

Penn State’s roster is better than Indiana’s, which should be enough to produce a victory. But the team’s first priority needs to be playing its cleanest game of the season to start the second half right.
