Tar Heel head coach Larry Fedora said he's pleased with the progress made by the unit overall, but there is still more work to do.
"They've been working on it all summer," Fedora said. "They knew what was going to happen today, they knew what the install was and those guys have taken care of themselves and they're prepared."
Fedora knows the team is nearing the end of the learning stages of this new defensive system.
"We're running out of time," Fedora said. "You can't tell yourself that lie that you have plenty of time because you don't. We don't have plenty of time, we're running out of time. There's a tremendous sense of urgency in what we have to get accomplished between now and then."
Consistency is the name of the game and Fedora said he wants to see it throughout the season, starting from Day 1 of training camp.
"You want to just see great effort today and great attitudes, and you want to see that everyday, that's what I just talked to them about. I want to see this on practice 16. I want to see the exact same thing that I saw today. If we can be consistent through camp then we'll be a much better football team."
