Staub, a 6-foot-3, 215-pound linebacker from Buford (Ga.), never deviated from the verbal commitment he made in mid-November, despite UNC's coaching staff change.
"It was an adventure," Staub said. "I'm glad I chose North Carolina. I think Coach [Larry] Fedora and his staff are going to do great things. I'm excited to be a part of it."
Since Fedora took over, Staub has had regular conversations with UNC assistant coaches Dave Duggan, Blake Anderson, and Vic Koenning.
"I was pretty firmly committed [when Fedora was hired]," Staub said. "But they just helped me realize I was going to be in good hands and that I was going to spend the next five years with good people."
UNC projects Staub, who has played inside and outside linebacker for Buford, to play middle linebacker.
Staub, who isn't participating in any sports this off-season to concentrate on preparing for his UNC career, says he's academically qualified according to the NCAA Clearinghouse.
