The four-star running back starred in the backfield over the past four years but will open his tenure as a Buckeye by hauling in passes instead of taking handoffs. Campbell, who is just 16 years old, is still growing and filling out his frame and the Ohio State coaching staff took notice.
"I'm going to be playing slot receiver starting out," he said. "But they told me it's all up to me how I adjust when I get there. They might bump me up and move me to running back later, but I'll be starting at slot receiver.
"It's just because of how I am right now, just because of my body type right now. They said I have a receiver's body right now, so that's where they're going to put me."
The 6-1, 180-pound speedster got a chance to show off his ability as a receiver when he caught a bomb and scored a 62-yard touchdown pass as his North team earned a 23-14 victory against the South in the Division I-III version of the Ohio North-South Classic on Saturday.
The play not only ignited him after a quiet start but also gave him confidence that he can make the move to receiver, which he didn't play much of in high school.
"Yeah, definitely," he said. "It felt good. I haven't had too many of those during the high school season, so it was definitely good."
With his last high school game behind him, Campbell will shift to focusing on what he needs to do at Ohio State. He'll have the company of high school teammates Dante Booker, who he said he classifies as a brother now, as well as a former Irish athlete in Doran Grant.
"I'm just going to go in with the mind-set to work hard," Campbell said. "I was talking to Doran Grant, who is kind of schooling me on some stuff. He just told me to come in and don't change anything I do. Don't try to overdo anything, just be myself. Just keep doing what I've been doing all high school season, and he said I'll be fine.
"It's really going to be hard, just because I'm going to see all the other guys around and think, ‘Oh man, he might be working harder than me.' I mean, it's definitely going to be hard."
Campbell is being discussed as a primary candidate for a position change because of the nature of his age – he'll turn 17 this summer – but he's going into Columbus with the goal of earning playing time as a true freshman.
"They tell me they think I'm very mature for my age, so they told me that's a good thing coming in," he said. "Honestly, though, they told me I should be fine and I shouldn't have anything to worry about. That kind of warmed me up a bit and made me even more excited."
