Some of you want to highlight Ryan Day's 2-7 record versus top-5 opponents. It would be relatively easy to "defend" Day's performance in most of those games, but I'm not his defense attorney. Instead, I want to take a look at how some previous Buckeye head coaches fared in big (and little) games:
Woody Hayes
In his last ten seasons, Hayes had six legitimate chances to win national championships and blew all six of them. He posted a losing record against Michigan (4-5-1) including dropping his final three Games; and in bowl games (2-6); and against top-5 competition (4-8-2, going 0-4-1 in his last five attempts). In addition, Hayes lost three games as the #1 ranked team in the country, once to an unranked opponent (Michigan State, 1974); and lost two games as the #2 ranked team, once to an unranked opponent (Missouri, 1976).

Earle Bruce
Bruce had one noteworthy season, 1979, his first in Columbus when he went 11-1 as Woody's replacement. In his remaining 8 seasons, Bruce compiled an uninspiring record of 70-31-1. Overall, Bruce had a record of 5-4 against Michigan; 5-3 in bowl games (but 0-2 in the Rose Bowl); and 1-3-1 against top-5 teams (his only win coming against #1 Iowa in 1985). In 1984, Bruce's #2 Buckeyes lost to unranked Purdue.

John Cooper
I will spare you the details and give you just a synopsis of of the Cooper Era: 2-10-1 versus Michigan; 3-8 in bowl games (but with two of those wins coming in "BCS" bowls); and 2-8 against top-5 opponents (with both wins coming in 1996, against #3 PSU and #2 ASU). Cooper never won a national championship but twice finished #2 in the polls (1996 and 1998).
Jim Tressel
Tressel is beloved by Buckeye fans for his 2002 national championship, his excellent record against Michigan (9-1), and his decent showing in bowl games (6-4, but just 1-2 in national championship contests). Against top-5 competition, Tressel compiled a record of 4-7; he lost his final six games against top-5 opponents, with his last win coming in the epic 2006 Game versus Michigan. Four times Tressel lost a game as the #1 ranked team in the country, twice in national championship games (2006 and 2007); once to #18 Wisconsin (2010); and once to unranked Illinois (2007). Tressel's worst loss came in 2009 when his #7 Buckeyes lost to an unranked Purdue team that finished the season with a record of 5-7. Tressel was fired after the 2010 season (all wins vacated) for lying to the NCAA.

Interregnum
As the de facto interim head coach, Luke Fickell compiled a record of 6-7 (3-5 in the Big Ten) with losses to Michigan and to Florida in the Gator Bowl; Fickell did not face a top-5 opponent.
Urban Meyer
Urban Meyer was arguably the best head coach in the history of Ohio State football: his overall record was 83-9 (.902 winning percentage), and he was 7-0 versus Michigan, 5-2 in bowl games (2-1 in playoff games), and 6-2 versus top-5 competition, with three Big Ten titles (2014, 2017, 2018) and a national championship (2014). Even with all that success, Meyer had a few unfathomable lopsided losses to unranked teams during his tenure in Columbus: 2014 to Virginia Tech (35-21); 2017 to Iowa (55-24); and 2018 to Purdue (49-20), with the losses to Iowa and Purdue costing Ohio State a spot in the playoffs.

Ryan Day
Despite having an overall record of 61-9, Ryan Day has developed a reputation for losing big games: he is 1-3* versus Michigan; 2-4 in bowl games; and 2-7 versus top-5 competition. However, unlike Urban Meyer and to some extent Jim Tressel, Day doesn't inexplicably lose games that he is supposed to win, with his "worst" loss coming against #12 Oregon in the 2021 season.
