COLUMBUS, Ohio — I knew preseason camp was officially back when Ohio State began running its 7-on-7 period away from the designated media section, and I had to peek through the reserve players to see what was going on.It’s always hard to determine who is winning between the receivers and defensive backs, but one pass stood out. I saw a ball floating well above everyone, and then out of nowhere, someone arrived and plucked the ball out of the air.It was five-star freshman Chris Henry who came down with the catch.“Whoa, Chris Henry’s catch radius is nuts,” I wrote down in my notebook.He ended up being one of a handful of receivers I was impressed with on the first day of practice. Topping that list were Henry, UTSA transfer Devin McCuin and freshman Brock Boyd.Ohio State has always had a wealth of talent at receiver, but leaving the first day of practice, I find myself considering that new assistant Cortez Hankton’s wide receiver rotation could change weekly — and I don’t think that’s a bad thing.The stars for Ohio State are poised for improvement this seasonCameron Teague RobinsonIt’s still early, and while the first team of Jeremiah Smith, Brandon Inniss and McCuin wasn’t a surprise, this corps has a chance to be a talented and deep group that extends beyond the headliner, Smith — maybe the best player in the country.Here are a few other takeaways from the first day of Ohio State camp.An offensive line move?Ohio State moved Austin Siereveld inside to right guard for the first practice, with Ian Moore taking over at left tackle.Coach Ryan Day said the Buckeyes will continue to experiment to find the best grouping, but it’s noteworthy that Siereveld — whose 809 snaps last year all came at left tackle, per PFF — made the move so quickly this summer, instead of waiting until the media sessions were closed.“We are going to try a couple different combinations,” Day said. “We are going to look at him playing tackle, as you saw last year, also look at him playing guard. … Finding the best five is what we’re going to do, but part of that five is knowing that Austin can play both guard and tackle.”The Buckeyes have options on the offensive line, like moving Siereveld back to tackle and swinging Josh Padilla to right guard, but that would be a more surprising move. All offseason, it felt like moving Siereveld inside was the best move for both his development and Ohio State’s future.The Athletic’s Dane Brugler recently ranked Siereveld as the No. 4 interior offensive line prospect for the 2027 NFL Draft.A rising star in a crowded secondaryThe assumption entering camp was Devin Sanchez was locked in at outside corner and safety Jaylen McClain was going to be the top safety — and likely a captain.Nothing happened Thursday to change those thoughts. In fact, when Sanchez sat down to talk to the media, he didn’t talk like a sophomore who was stepping into his first year as a true starter; he spoke like somebody who believes he’s the No. 1 corner.“You know I got to go out there and guard Cam Coleman for probably 70 snaps and got to do that every play,” Sanchez said of Texas’ star transfer receiver. “I feel like these guys are counting on me, I’m counting on myself and my family is counting on me. It’s a big task, it’s a lot that comes with it, but it’s for a guy like me who is not scared of it.”That’s the type of confidence coaches love to hear coming from cornerbacks, especially one who was a five-star recruit. Confidence only goes so far if it can’t be backed up on the field, but Sanchez had a strong offseason and looks different than the freshman who showed up last year.“I feel like my old self. I feel very comfortable out there,” Sanchez said. “I’m very confident that I can go out here and play with anybody in the country.”There are still questions about what the secondary will look like around Sanchez and McClain. Jermaine Mathews Jr. is back at outside corner, but Georgia transfer Dominick Kelly also got a lot of time with the starters Thursday. Five-star freshman Jay Timmons can’t be overlooked, either.“We’re just rolling guys right now, but it is a competition and we want guys to compete,” Day said. “Now’s the time when we will be rolling these guys, these reps will accumulate, we evaluate the reps and see where it goes. We’ve seen certain competitions be over in a week, we’ve seen them last up until game week, but we need to find what that combination is going to be there.”If four cornerbacks could see time and three safeties with McClain and transfers Terry Moore and Earl Little Jr., then somebody is going to be left out at the nickel position. When Ohio State added both Moore and Little in January, it was assumed the Buckeyes would use a three-safety set. That still may be the case, but the emergence of Kelly and even Timmons may complicate things.“Do we feel like we have two corners we can just play all the time? Do we feel like there’s three that can rotate? How does that play into the nickel position?” Day said. “Those are all parts of what we need to solve here in the next couple weeks.”Much like the receivers, the secondary could look much different from week to week this season.First look at the defensive line rotationWith no pads or tackling, it’s hard to evaluate the defensive line, but the four playing together in Ohio State’s team period were ends Kenyatta Jackson and Beau Atkinson and tackles Eddrick Houston and Will Smith Jr.Multiple battles along the defensive line are far from over, but left guard Luke Montgomery raved about the entire group after practice.It was notable that Ohio State, which ran a lot of three-linebacker looks on Thursday, had both Christian Alliegro and Riley Pettijohn positioned on the ball at times. There’s a lot of flexibility at linebacker that could help the defensive line.Who was missing?There was one notable absence from practice: Freshman running back Legend Bey did not participate.Day said Bey is suspended for the first few practices after violating team rules.“He’s learning, but he’ll be back on the field soon,” Day said.Bey has been a fan favorite on social media, not just because the Buckeyes beat out Tennessee for the speedster, but because his athleticism is something that can be used at running back or receiver.For him to get on the field, he needs to practice. Now he’s facing a setback. Day did not say how long the suspension would be.
