COLUMBUS, Ohio — As the weeks pass and the upsets mount, the Buckeyes are ascending in the polls.

They’re up to No. 5 this week, are one of three Big Ten East Division teams still unbeaten in league play and on the verge of being in the playoff discussion.

But it’s all contingent on the Buckeyes continuing to win.

Indiana, meanwhile, opened this season by pointing to this contest as a potential ticket to the conference championship game. Instead, they’re simply trying to prove they can finally beat the Buckeyes.

KEY MATCHUP

Hoosiers receivers vs. Ohio State defense. Indiana has had multiple problems on offense but one of the biggest has been drops.

Coach Tom Allen even brought it up publicly after last weekend’s loss to No. 10 Michigan State.

Despite recording nine interceptions this season, the Buckeyes rank near the bottom of the Big Ten against the pass. Indiana must clean up the catches and take advantage of the Buckeyes secondary to have any chance.

PLAYERS TO WATCH

Ohio State: QB C.J. Stroud. The freshman phenom has played lights out, leading the Big Ten in passer efficiency rating (191.2) while working with the dynamic receiving combination of Garrett Wilson and Chris Olave. This week, he needs to take advantage of an Indiana secondary that has been severely depleted by injuries.

Indiana: WR Ty Fryfogle. Last season’s Big Ten receiver of the year has struggled to duplicate that success. Sure, he has 33 receptions, 337 yards and one TD. But it’s the missed opportunities that have created consternation. Fryfogle must become a more consistent pass-catcher in the second half of the season.
