KNOXVILLE - His debut out of the way, Derek Barnett now might as well be a veteran.

The Tennessee freshman defensive end believes it's time he plays like one, at least.

After becoming Sunday the first true freshman to start a season opener on the defensive line for the Volunteers in the history of the program, Barnett already was thinking ahead to the next step in his development.

"I feel good I got that first game out of the way," the Nashville resident said after Tuesday's practice.
