After sleeping on it, not really sure what to think. This could've simply been a battle between the two clear best teams in the country and Indiana made one more play than OSU while the Buckeyes didn't play near their best. I have no more real concerns with the defense. The only playoff team with a better offense than Indiana is Ole Miss, and their defense is ass. Plus there's the whole Kiffin nonsense.
Offense scares me a lot more after this game and it's mainly because of play calling. OL and Sayin didn't play great in the first half but they seemed to settle down in the second half. The red zone play calling in the second half was coaching malpractice and it's something we've seen with Day through out the years. Multiple times with 3rd and 1 in the red zone only to piss it away with a dumbass passing play.
If this was like the Texas game where the lack of execution was more of a problem, I'd feel a lot more confidence going into the playoffs.
