"So he's going to have to work hard with our defensive line coach to learn techniques of all four spots. And he's going to have to be able to line up at all four spots on all four downs. I don't want the offensive coordinator or head coach on the other side of the field to know where he's going to be."
Last season, Stanley lined up at both strong-side and weak-side end. The 6-foot-3, 253-pounder ended the season with 83 tackles, including 16 for a loss and eight sacks.
On the collegiate level, though, Stanley will play defensive tackle.
"He's big, he has long arms," Kelley said. "He has the potential to put on the 20-30 pounds necessary to play defensive tackle on the ACC or SEC level."
Stanley has already quietly collected scholarship offers from Arkansas, Duke, and East Carolina. He's also receiving varied interest from Boston College, Clemson, North Carolina, Wisconsin, and Virginia Tech.
"The two things that stick out in my mind about Terrell: No. 1 is his tenacity on the field," Kelley said. "I don't believe I've seen too many kids that hate to lose as much as he does. And No. 2 is how hard he plays. He really hates to lose and he really plays hard."
Another thing to keep in mind with Stanley is he's young for his grade – he's currently a 16-year old junior.
Stanley's early favorite school is Duke.
"I like the coaches and the education you'll get if you go there," Stanley said.
Duke is one of two schools Stanley has visited – the other being NC State for a football game. Before even thinking about making a verbal commitment, Kelley wants Stanley to take more visits, starting with an April trip to Arkansas.
"I want him to see Arkansas," Kelley said. "I want him to see some of the things outside of North Carolina."
Stanley also plans to visit East Carolina this spring and is considering accepting Boston College's invitation to visit its campus.
This summer, Stanley says he will likely camp at Duke and NC State.
