The first half should generally be enough time to put away a team that is in the bottom quarter of FBS teams. Maybe Arkansas State is a little better than that, but usually Ohio State is up 35-0 or more against teams like that by halftime. They were up 13-6 over Tulsa last year, which was clearly disappointing. They were up 38-7 vs. Akron last year, which I think is more along the lines of expected results.
Tulsa turned out to be a little better than thought last year, so maybe Arkansas State is the same. It may be the year of the Sun Belt afterall.
