Grassilli, a product of Woodbridge (Va.) Hylton High School, yet again had a solid camp performance but did yet not land a UNC offer.
"I did really well during the one-on-ones and everything else," said Grassilli. "They didn't offer me after the camp, but they are looking to see how I do during the season.
"I talked to [Thigpen] afterwards and he said I was a great athlete, I did really well in the one-on-ones and everything else and the coaches are interested, it's just they want to wait awhile. He told me there were other guys there that already had offers to other schools, so they offered them. He said once things get rolling with the season, they'll come back looking."
From the start of the June camp to the end of the July camp, Grassilli has made huge strides in his progression because of his strong worth ethic.
"I felt that [I progressed] and Coach Thigpen was really impressed with my [40-yard dash] time – it went down two tenths of a second," said Grassilli. "Everything I got a lot better. I gained weight. In the one-on-ones I got a lot better – my steps were a lot better and my punch."
An added benefit to attending the Tar Heels' camp was working closely with new offensive line coach Mark Weber.
"I liked his technique that he coached," said Grassilli. "When he showed me how to do them and when I started doing them, I found they really worked well for me – they really helped me. I liked the guy. I think he's really going to bring a lot to the program. He really impressed me."
Grassilli has also camped at Boston College, Notre Dame, Penn State, and Virginia Tech.
Despite the lack of a Division I-A scholarship offer, Grassilli lists three schools as early favorites.
"Right now, the schools I really like are Stanford ( I've been talking to the coaching staff), Notre Dame (they like me and they said if a spot opens up then they'll look at offering me) and Penn State," said Grassilli.
Although he doesn't list UNC among his top three, North Carolina is very much on his mind.
"I like the program, I like the way they treat the players," said Grassilli.
During his junior season, Grassilli struggled keeping on weight but still landed on the All-District Second Team.
