This running game debate is fruitless...neither PSU nor OSU has been stellar.
So, the passing game has to compensate then. As of this point (and frankly the last decade), OSUs 'WR' room has carried their bacon when times have gotten tough in big games.
Entering next week's game, that room (based on star rating) will be the best on the field of any position by both teams, and it isn't close. But, PSU enters with more than enough ability and defensive talent, especially, to get the job done. Should be a battle.
