Josh on College Football Nerds laid it out pretty well in their review. Basically, over-matched teams can either play straight up (i.e. with their normal tendencies), hope to keep the score manageable and hope the other team makes enough mistakes to win. Or, they can go off tendency and become very aggressive.
For Bucky, the script on playing tOSU straight up was written as 38-7. They know that won't work. Plus, they saw both PSU and TTUN moved the ball on us in the passing game, not consistently, but still enough to get some yards.
Finally, in their own game against Minnesota, Bucky did very well moving the ball through the air, including a few successful deep balls against a pretty good defense.
So I expect them to go the very aggressive route. It's really the only shot they have. A lot of deep balls, certainly some TE passes (duh!). On defense I expect a lot of stunts (which they did a lot last time) and more blitzing. Wouldn't be surprised at a fake punt or onside kick. They're only hope is to throw haymakers and hope to get tOSU in their heels.
But I don't think it will work. The down side of playing super aggressive is that it leaves you open to turnovers and bad field position and big plays if your blitzes don't get home, and you could end up getting blown out, obviously. It might work for a play or two, but this Ohio State team has actually played quite disciplined this year, they'll be ready for it. I expect to win the turnover margin by 2 with a defensive score in there.
Is say 52-20 with the Chug and Teague show in the 4th.
