RALEIGH, NC (AP) - Defenses in the Atlantic Coast Conference aren't waiting for passing situations to bring on another defensive back.
Instead, they're starting with the nickel package.
It's an effort to cover more ground and avoid mismatches against offenses that keep flooding the field with receivers and attacking from sideline to sideline without substituting.
Duke, Georgia Tech, North Carolina, North Carolina State, Virginia Tech and Wake Forest are using a 4-2-5 - four linemen, two linebackers and five defensive backs - as their base scheme and the starting point for what they do every week.
Other teams are using the nickel heavily, including reigning national champion Florida State.
Georgia Tech defensive coordinator Ted Roof says the game has evolved, and now defenses are trying to match up and disguise coverages with the nickel.
