In addition to giving Robertson more options – and more campuses to visit, the new offers also present a different position option for Robertson.
"Clemson wants me to play outside linebacker and that's completely different from what other schools want me to play," said Robertson, who is mostly being recruit for defensive end.
"[With North Carolina I like] the coaches, they treat me so well there; just the environment that Carolina has; and I got so many friends at Carolina that if I go there, they can show me around.
"[With N.C. State I like] their defense – the defense that they had and they're working on a good defense now. They're trying to turn the program around. They got friends there that give me a lot of good advice not just about N.C. State, but other schools.
"The coach that left [North] Carolina [Brad Lawing] that was recruiting me, he's recruited me at South Carolina. He's about the same as he was at North Carolina. He likes me more than just a player."
Before verbally committing, Robertson hopes to unofficially visit both of his new offering schools. He has already taken trips to UNC, NCSU, and USC, and plans to revisit both Chapel Hill and Columbia this summer for camp.
A Scout.com four-star defensive end, the 6-foot-4, 220-pounder missed all but three games his junior season with a knee injury but still totaled 11 tackles and three sacks for Laurinburg (N.C.) Scotland County.
