Vic Koenning keeps an open Bible on his desk and speaks warily of pride.

"In the Bible," said Koenning, the associate head coach for defense at North Carolina, "they say pride comes before destruction. So you try not to have pride."

He is speaking about his role in the evolution of the 4-2-5 defense, which the Tar Heels will run in their first season under Larry Fedora. Koenning didn't invent the 4-2-5, nor did he perfect it. And even if he had, he says, it wouldn't be for him to say.
