A linebacker from Lithonia, Ga., M.L. King High School, Mack is on the watch list for Class 5-A state honors in Georgia and is primed for a big senior season.
The 6-foot-3, 200-pound Mack has switched from defensive end into the middle at linebacker and said he's going for his goal of 100 tackles.
"I want to be an All-American," Mack said. "I had to improve certain things, like my coverage and also coming down and reading plays. But I'm ready.
"My team, we want to win a state championship and we all need to come together for that to happen. I'm excited for this season, it's going to be fun."
Mack said the move to linebacker hasn't been a tough as he expected.
"I don't think LBer is that hard," Mack said. "I already have the speed and athleticism. It all just came natural to me this year at linebacker. I feel like I have dominated so far in practice."
Mack committed to Louisville in March before he stepped foot on campus. He made a visit to U of L this summer for camp and said he's "100 percent committed."
"It was way more than I expected when I was there for camp," Mack said. "I went to some other schools, like Florida, and the dorms were nothing like they were in Louisville. I just really liked it there a lot."
Mack said he's been keeping in touch with the U of L staff, including linebacker coach Brian Jean-Mary, and several other commitments.
"(Quarterback commitment) Kyle (Bolin) and I talk every now and then," he said. "We'll tweet each other and have a conversation. It's nice to know somebody."
Mack said he has passed all his summer classes and the plan now is for him to enroll at U of L for the January session of school.
