CHARLOTTE, N.C. -- On at least one play during Sunday's 24-7 victory against Detroit the Carolina Panthers lined defensive ends Charles Johnson and Mario Addison in the middle at tackle in order to create more quarterback pressure.
It's called, appropriately, "NASCAR."
"We put four guys out there and say, 'Go fast,'" coach Ron Rivera said on Friday.
The formula is simple, and one that might have to be used more to apply pressure with 2013 sack leader Greg Hardy on leave of absence until his domestic violence case is resolved.
The intent is to put as much pressure as possible on the quarterback with the front four, allowing the linebackers to drop into coverage. It works hand-in-hand with the cornerbacks being physical with wide receivers in the first five yards, to throw off the play's timing.
It's a philosophy that helped Carolina lead the league in sacks last season with 60, without having to blitz a lot.
Rivera said there will be times when you will see defensive tackle Kawann Short surrounded by three ends, or four ends and no tackles. It will always be the fastest and freshest players the Panthers have in obvious passing situations.
Regarding fresh, Rivera said he has to find a way to cut down on the snap counts for Johnson. With Hardy out against Detroit, the team's third all-time leader in sacks (54) was on the field for 62 of 72 defensive snaps.
That was 18 more than the next defensive lineman and 28 more than the next end.
Johnson was double-teamed much of the time because the Lions didn't have to worry about Hardy on the other side. He had no sacks for the game and has none for the season.
"Will he continue to get doubles like he did last week?" Rivera said. "If he's getting doubled, then other guys have got to step up, a la what happened with Mario [2.5 sacks]."
Among others Rivera cited as needing to step up was second-year tackle Star Lotulelei, who also has no sacks.
"We're going to be physical," Rivera said. "We're going to buy that extra step. But we want the four fastest to go, just to get up in there and haul butt."
Rivera said he likely will stick with the rotation he used to replace Hardy at right defensive end against Detroit. Wes Horton started and played mostly on first and second down. Addison played mostly on third down and pass rush situations.
Second-round draft pick Kony Ealy began mostly on third down, but worked more into the rotation on first and second. He could be used to give Johnson a break.
"We've got to be smart," Rivera said. "One of the things we've got to be aware of is that we don't wear Charles out."
