Savor it now.

Before long, it will increasingly become a rarity.

No. 3-ranked Ohio State hosts No. 7-ranked Penn State on Saturday (noon, Fox) in what will be a season-defining game for both Big Ten teams.

Both teams are undefeated at 6-0, and the result likely will dictate their College Football Playoff outlooks. A loss significantly hurts their chances to earn a playoff bid, relegating the loser to a long list of strong one-loss teams trying to prove their résumé is superior.
