​As preseason camp begins this week, Land-Grant Holy Land is diving into its final theme every week of the off-season. This week is all about identifying one specific thing sure to make a difference for the Buckeyes this fall. You can catch up on all of the Theme Week content here and all of our ”The One Thing” articles here.Since taking over as head coach following Urban Meyer’s retirement, Ryan Day has posted a 79-12 record as head coach of Ohio State.AdvertisementAdvertisementAdvertisementWhile Day has been in charge, the Buckeyes routinely have fielded one of the best offenses in the country. It doesn’t hurt that Day has had quarterbacks like Justin Fields, C.J. Stroud, Will Howard, and now Julian Sayin running the offense on the field.Along with the quarterbacks there have been an amazing collection of wide receivers who have gone on to be first round picks in the NFL Draft, as well as great running backs like TreVeyon Henderson and Quinshon Judkins.During the first half of Day’s tenure as head coach, Kevin Wilson was the team’s offensive coordinator, serving for four years under Day before becoming head coach at Tulsa.

Originally former Penn State and Houston Texans head coach Bill O’Brien was hired as the offensive coordinator, but O’Brien would take the head coaching position at Boston College less than a month later.To fill the vacancy left by O’Brien, Day hired his mentor, Chip Kelly. The combination of Kelly and experienced quarterback Will Howard were a major reason why the Buckeyes were able to win a national title in 2024.AdvertisementAdvertisementAdvertisementThe title run by Ohio State resulted in the Las Vegas Raiders shelling out a bunch of money to convince Kelly to return to the NFL as the team’s offensive coordinator. With Kelly leaving the program, Day decided to give Hartline another shot at offensive coordinator.This time things seemed to click for Hartline, as Julian Sayin and the Buckeyes were surgical on offense for most of the season.The downfall for Ohio State last season started when
