The top three ACC quarterbacks.

1) Danny O’Brien, Maryland

With an advanced mental acumen and a tireless work ethic, O’Brien is poised to improve after a redshirt freshman season in which he threw 22 touchdown passes, the second most in a season in school history.

2) E.J. Manuel, Florida State

An elusive runner, Manuel takes over the job full-time after the departure of Christian Ponder. The junior has completed 67 percent of his passes in 14 game appearances.

3) Logan Thomas, Virginia Tech

The ACC has its share of uncertainty at the quarterback position. But Thomas, an athletic specimen, gives the Hokies an X-factor as they navigate a somewhat soft schedule.

These three defensive players are the biggest threats to ACC quarterbacks.

1) Quinton Coples, DE, North Carolina

The senior could be the nation’s most dominating defensive end after moving back to his natural position. Coples ranked third in the league in sacks per game while playing tackle last season.

2) Brandon Jenkins, DE, Florida State

Jenkins ranked third nationally in total sacks as a true sophomore. His 13.5 sacks tied for fifth-best in school history. With blazing quickness of the ball, Jenkins is one of the nation’s elite rush ends and a nightmare for quarterbacks.

3) Kenny Tate, LB, Maryland

The senior should excel after moving from safety to Star, a hybrid outside linebacker-safety position. The combination of size and speed makes Tate a ferocious tackler.
