"I was meeting with (head coach Jim) Tressel in his office," Carter told BuckeyeSports.com. "He was happy. I think he was the only person that was happier than me. It was a great moment."
The 6-4, 325-pound Carter issued his commitment while on OSU's campus today for an unofficial visit. Accompanied by his coach and parents, Carter was able to get the day off from school because students were taking the Ohio Graduation Tests and he passed all of his last year.
Carter said he knew he wanted to be a Buckeye as soon as he landed a scholarship offer from them about two months ago.
"I wanted to make a well-informed decision," he said. "There was always in my mind that I wanted to go to Ohio State but first I wanted to make that informed decision. I wanted to see the campus. I was told how the academic support system was, but I wanted to see it and ask questions for myself."
Once he got to campus and looked around, Carter pulled the trigger.
"When I toured the facilities, we took a tour of the campus and the various facilities and I liked it," he said. "I liked the fact that the coaches were real and they care about you."
Carter also held offers from the likes of North Carolina State, Miami (Ohio), Toledo and Akron, among others. He said USC, Michigan and Syracuse had been calling recently and that he had started receiving mail from Wisconsin, Kansas State and Iowa State.
None of them could beat the Buckeyes to the punch.
"I thought Ohio State was going to be one of the last offers I was going to receive but Ohio State was the first," he said. "It made it easy and showed me how much they wanted me."
Asked what his reaction was when he landed an offer from the Buckeyes, Carter said, "It surprised me a lot. I felt like doing cartwheels but I'm too big to do cartwheels."
Scout lists Carter as an unranked offensive guard prospect. He said the Buckeyes are primarily looking at him as a guard but that he could potentially shift outside to tackle as well.
A member of the Senate Athletic League, Carter's teammates play in the shadow of Cleveland Glenville and the program's annual output of Division I talent. Carter's hope is that his recruitment will help open up more opportunities for players within the conference.
"Not being from Glenville but still having Big Ten offers and going to a Big Ten school that recruited me, it shows the rest of the conference that Glenville is not the only one that can produce prospects," he said.
In addition, he said his commitment figures to have a positive impact on his community.
"It's an opportunity to help a winning program do what it does best," he said. "As for my community, I'm pretty sure no one in my community has ever seen a Buckeye. I'm pretty sure of that."
Those sound like some big expectations to live up to, but Carter said he is up to the challenge.
"I've always had to live with big expectations," he said. "I'm 6-4, 300-some odd pounds. I've always had the expectations to go to Ohio State and then go to the NFL and then come out of the NFL, retire and live somewhere in Arizona.
"It feels good. I'm an official unofficial Buckeye."
