COLUMBUS, Ohio — Monday marked the last day of No. 1 Ohio State’s preseason camp, and though Ryan Day didn’t finalize a starting offensive line, he provided the biggest update since practices began.Day said that former left tackle Austin Siereveld, who was named a captain for the second straight year, has been practicing at right guard for most of camp. That discussion wasn’t an easy one, especially with Siereveld’s 788 snaps at left tackle last year, per TruMedia, but Day said most of the staff sees Siereveld as an NFL-caliber guard.The senior will hope to fill a void that was the weak point of the line for the Buckeyes a year ago. The move has opened up the left tackle position for Ian Moore.Moore, a junior former four-star prospect from New Palestine, Ind., has been playing left tackle with the starters for much of camp and will likely take that position going into the season. This will be Moore’s first year as a starter, but the coaching staff is high on Moore due to his size and movement on the edge.“He has the size, athleticism and now we get more experience,” Day said of Moore. “It’s been good to see him go against our guys in practice to give us an idea of what it’s going to look like. Everything has been trending coming into the summer and we think he’s continued to get better.”9.5 wins for Ohio State in 2026?Ralph D. Russo and Stewart MandelThose two lineup changes will give Ohio State the potential starting line of Moore at left tackle, Luke Montgomery at left guard, Carson Hinzman at center, Siereveld at right guard and Phillip Daniels at right tackle.That’s four returning starters who each played at least 740 snaps last year, plus Moore.“When you look at Luke, Carson and Austin inside, that’s a lot of beef right there,” Day said. “ It certainly has given us a lot of reasons to like that, as long as the tackle play is good, which so far it has been.”And on paper, with four players returning with more experience and Moore stepping in, this unit is an upgrade from last year’s offensive line that gave up 10 sacks in the postseason to Indiana and Miami.Day won’t go on record officially saying that’s the offensive line for the Sept. 5 opener against Ball State, but he said that’s how things are trending.The concern now isn’t a talent issue; it’s about how fast they can gel and execute new offensive coordinator Arthur Smith’s scheme.What’s the deal at tight end?As camp comes to an end, Day and the Buckeyes have sorted out how much they want to cut down on their positional rotations.One of the biggest unknowns on the offense is how many tight ends will play. Last year, Max Klare and Will Kacmarek dominated playing time, with each over 470 snaps and nobody else playing more than 250. It seems like those snaps will be broken up a bit more.Day thinks Bennett Christian, Nate Roberts and Mason Williams are three tight ends who will play often. How many are on the field at one time will depend on the game plan and personnel scenarios.“Those guys can do multiple things, whether it’s in 11 personnel or 12 personnel,” Day said. “I think those three have separated a little bit from the rest of the group, but we’ll see how this week plays out.”Ohio State has used each of them on the line or in the slot this summer, which should open up Smith for some creative play calls.The rest of the group, including Northwestern transfer Hunter Welcing, is filling out depth positions, he said.How often Ohio State uses multiple tight ends will remain unknown until the Ball State game, but Day sounds confident in the position, despite losing two second-day NFL Draft picks last spring.How many WRs will play?We’ve known for some time that the Ohio State receiving corps is deeper despite the loss of No. 4 pick Carnell Tate.“Our depth at wide receiver is way better than it was last year,” Day said. “There’s a lot of guys you’ll see play.”Day seemed pretty relaxed on Monday, so much so that a reporter asked him about his demeanor and he joked that he’s “pissed” about everything actually. But the way he’s talked about the receivers this summer should create confidence in a fan base that has become accustomed to elite play from the receivers.Though LSU transfer Kyle Parker is not 100 percent back at practice, Day said he thinks six receivers could see major playing time this year. Those six would be: Jeremiah Smith, Brandon Inniss, UTSA transfer Devin McCuin, Parker (when healthy) and freshmen Chris Henry Jr. and Brock Boyd.Day also went down the line to add in some depth players like Phillip Bell and Dezie Jones.“They’ve been having a good camp, because they’re working hard out there,” Day said. “It’s showing up and there’s been good competition on both sides.”Is there a backup QB competition?Freshman Luke Fahey has been making headlines after losing his black stripe midway through preseason camp.The three-star prospect entered camp with the assumption that his first year would be about development, as he took over the third- or fourth-string role, but after the first scrimmage Day said Fahey has been pushing former five-star recruit Tavien St. Clair for the backup role. And Fahey continued his good play in last Saturday’s scrimmage, as well.“He can handle all the stuff that’s coming with the quarterback in terms of the protection checks, the run checks, calling it out of the huddle and calling the line of scrimmage,” Day said. “Then he has good anticipation and feel on the field, knows time, situation and score and has good awareness.”That’s still the case.Day was not ready on Monday to name a backup to Julian Sayin, adding that he wants to see how Fahey and St. Clair compete this week before making a decision for game week.The backup quarterback position isn’t the biggest news regarding Ohio State’s immediate national championship hopes, but St. Clair is among the highest profile backups in the country, as the No. 3 quarterback of the 2025 class has always been expected to be the next man up whenever Sayin leaves. This year of development is crucial for him.
