Clark, a 6-foot-3, 205-pound athlete from Cleveland (Ohio) Glenville, will also "definitely" officially visit California and is considering official trips to UCLA and Wisconsin.
California and UNC are Clark's lone BCS scholarship offers and his co-leaders.
"It's kind of equal right now [between Cal and UNC]," Frank said. "Yeah, I'll say it's about equal, really, because they're offering the same thing but offered me to play two different positions."
UNC is recruiting Clark as a linebacker/strong safety, while California likes him as a wide receiver.
"I had planned on playing wide out in college, but I'm an athlete," Clark said. "I'm a wide out, but I love playing defense, also.
"At the end of the day, it's going to be how I feel what's the best position I'm going to be able to play in college [and] what's going to get me paid professionally – what's going to get me to the league eventually."
At Glenville, Clark plays tight end, wide receiver, linebacker, strong safety, and handles kickoffs.
Clark was born and raised in Los Angeles, but has a lot of family in North Carolina. Thus, location won't play a role in his collegiate decision.
"I love playing in warm weather," Clark said. "I love the heat. I love practicing in the heat."
Besides California and UNC, Clark has collected offers from Eastern Michigan and Toledo.
"And there's a number of schools just waiting," Clark said.
Kansas, Kentucky, Michigan, Michigan State, Oregon, UCLA, USC, and Wisconsin are among the schools "just waiting" for more film before offering Clark.
Clark earned his UNC offer during the Tar Heels' camp this past summer. Initially, as part of Raw Talent, which was a group of recruits who traveled the nation attending camps, Clark participated in the first session of UNC's two-day camp as a receiver. At the UNC coaching staff's request, he returned the next day alone and worked out at linebacker.
"Honestly, I thought ‘I'm going to be the only player coming back from my group [and] this could be a waste of time,'" Clark said. "But I'm a football player – I hate when the season ends. So I came back excited. So I just went up there and gave it my all."
The decision to return yielded Clark his first BCS scholarship offer.
"My coach/trainer, Mark Harris, kept telling me ‘I told you, I told you, I told you,'" Clark said. "I was like ‘Yeah, you told me.' I am glad I went back."
In addition to the offer, the return visit gave Clark a better feel for UNC.
"It was a family-like atmosphere," Clark said. "It felt like I was at my own practice, because when I was there, they treated me like I was their No. 1 recruit, after I came back for the second day.
"After camp was done, they brought players on the field like Greg Little [and] Bruce [Carter]. They were like ‘Come take a tour with us.' But my coach was like ‘We've got to go.'"
Clark plans to tour the campus and get to know the UNC coaches better during his official visit.
