"It means a lot to me. It just goes to show that even after my senior high school season, I still work hard. I want to be here," he said of the honor.
Drennon is the lone athlete from New Jersey playing in this week's game and is looking forward to compete alongside some of the nation's top prospects.
"I'm hoping to play against bigger guys. The people we go up against in New Jersey aren't as big as these guys are, so it gives me a challenge to play with players who are as good as I am, and better.
"I'm the only person from New Jersey here, so I get to put it on for my state and battle it out against guys from different states. It feels good to be here. I get to see what football is like everywhere else," he said.
The 6-foot-4, 235-pound prospect is one of three future Tar Heels participating in the game and Drennon has enjoyed spending time with offensive lineman R.J. Prince and fellow defensive line prospect Nazair Jones.
"I love it because I never got to meet those guys, so this is my actual chance to hang out with them and see what they are about on the field," he said.
In August, Drennon committed to the Tar Heels over a number of other programs and still feels confident with his decision.
"I chose North Carolina for two reasons. First, because one of my best friends, a player from my school, Greg Webb, is also a North Carolina commit, so we're going to go there together. And I just love it down there: the weather, the campus. Just to have a degree from North Carolina is a big deal," he said.
He's also looking forward to using his talents to help the Tar Heels on the field over the next few seasons.
"A lot of guys may be bigger and stronger than I am, but I just like to beat them with my quickness. I'd say my speed is my biggest strength," he said.
This week's roster is comprised of players who will be joining programs from almost every major conference, and Drennon has enjoyed representing both the ACC and the Tar Heels.
"There's a lot of trash talking," he laughed. "We just want to prove that what we're going to do at our school is better than what they will do at their school."
