North Carolina's defensive coordinator said his players have retained information well and the defense is about 80 percent installed, but there is still work to be done.
"The thing you look at when you're new is the retention rate from the spring going into the fall," Chizik said. "The work that they put in over the summer on their own is huge. It was evident that they really put the work in."
Chizik is not the only one who has noticed the extra work players are putting in. Quarterback Marquise Williams has also emphasized how much more frequently his teammates on both sides of the ball have worked out outside of practice.
This additional work is a testament to the drive the players have and their desire to improve, both points Chizik touched on during Media Day. He also stressed the importance of being physical and the large part physicality plays in having a successful team.
"Everything in this game is about physicality. I have not ever been around a good defense that's not physical, never."
Increased physicality and tackling are the two main points of improvements Chizik addressed.
