Due to a death in the family, Gray hasn't been available for comment the past couple of days.
Gray, a 6-foot-3, 295-pound defensive tackle, jumped onto UNC's recruiting radar late in the process.
"Coach [Tommy] Thigpen at Auburn – he was a coach at North Carolina – talked to Coach [John] Blake [about Gray]," Glover said. "[Thigpen] knew about Carlos, because I had taken Carlos down there [to Auburn]."
That recommendation led to Art Kaufman visiting Pinson Valley High roughly two weeks back to observe Gray at basketball practice.
"[Kaufman] was just in awe," Glover said. "Athletic wise, [Gray] is as athletic as any big kid there is. He's almost 6-3, 295 [pounds] and can stand flat foot and can dunk a basketball with two hands behind his head."
A week ago, Kaufman returned to Pinson Valley High accompanied by Blake.
"[Blake] loved him," Glover said. "He watched film on him. The potential is there. [Gray] is as raw of a kid as you're going to find. But athletic wise and the way he moves, he doesn't move like he's 300 pounds."
Gray was then invited to officially visit UNC this past weekend (Jan. 29). He was already scheduled to visit Mississippi State officially that weekend. But, he canceled the trip.
"He liked Coach Blake and Coach Kaufman and wanted to see what [UNC] was about," Glover said.
Besides Mississippi State and UNC, Gray received interest from La Tech – until head coach Derek Dooley left for Tennessee – and early interest from Alabama.
"Coach [Nick] Saban brought him in his office and told him ‘You're more athletic than anyone on our team, I want to see you do good things, do your part,'" Glover said. "But they pulled off of him just because of the fact [Saban] watched his film and nothing is going to stand out."
According to Glover, Gray's senior football season was mediocre at best.
"I got in here late as a coach and [Gray] was allowed to be lazy, basically," Glover said.
Additionally, up until recently Gray hadn't taken the ACT or SAT.
"He's good [with the ACT score]," Glover said. "He's going to have to bring his core [GPA] up. But it looks like there's not going to be any problem with that… As long as he does what he's supposed to do, he'll qualify and be there in the summer."
