"Tennessee offered [last] Monday," said Robertson. "A lot of schools came down [to my school] on Tuesday, but most of them had already offered."
The Volunteers join North Carolina, N.C. State, South Carolina, Virginia Tech, and Clemson on Robertson's offers sheet.
Once considered a huge North Carolina lean, the constant flow of offers has forced Robertson to completely open up his recruitment.
"It's open right now," said Robertson. "There's so many [offers] now. I've been talking to so many [schools] it changes my mind about everything."
Robertson is, however, sticking to his plans of verbally committing before the start of his senior football season.
Prior to committing, Robertson will attend summer camps at Florida, North Carolina, and Virginia Tech to get a closer look at each school.
This past weekend Robertson participated in his first competitive football related event since last fall's knee injury when he attended the Shrine Bowl Combine held in Jamestown (N.C.).
"I'm not trying to push too much today," said Robertson Saturday. "I'm not yet 100%, that's what's stopping me today. The doctors, they didn't recommend me to come out here to mess it up."
Worries of re-injury forced Robertson to skip events like the 20-yard shuttle and vertical jump, but didn't prevent the 6-foot-4, 220-pounder from posting impressive times in the 40-yard dash (4.58 seconds) and bench press (19 repetitions of 185 pounds).
A Scout.com four-star defensive end, Robertson 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.
