After a 4-0 start, Mack got the news from teammates that coach Kyle Flood offered him his first scholarship.
"I went back to my mom and everybody was making noise, ‘congratulations' and stuff," Mack said. "She told me Rutgers offered me. I was shocked. I never thought it would come this early. I thought I'd have to wait on it. Working hard pays off. It's very cool. I just came out here to play the game, and train to be the best. I was really surprised, but I've been working hard in the weight room, and I know what I can do."
Mack is a 6-foot-2, 175-pound receiver. His teammate, 2015 defensive lineman Kamaal Seymour, is a Rutgers commit. The passing camp marked Mack's third visit of the year to Rutgers.
"My sister is coming here too," he said. "The fact that I could be with my family and also get experience playing D-1 football at a great school, it's a great feeling."
Mack also visited Rutgers for its skills camp earlier in June.
"It actually is a very good school," he said. "When I came for the wide receivers camp, I learned a lot. They took me on a mini tour of everything. They told me all about their history. It was nice to get to know more about them."
