Chris Collins is putting on weight, but hasn't lost any quickness in the process. 

After adjusting to Jay Bateman's defensive scheme in the spring, he feels like the Heels are ready to roll.

"I feel like in the spring it was a little bit challenging, because I was new to it," he said. "Everybody was new to it, as a defense, and we’ve had a whole summer to rep it. Now, everybody is getting the hang of it."
