This defense uses a stunt between the strong side DE and the N to try to confuse the offensive line.

It is important for the DE to cheat in to line up in the B gap to allow him to execute the veer technique through the offensive guards neck to the A gap.
The N should line up in the A gap and loop behind the DE to allow him to get out to the C gap.
The strong-side LB (S) can line up anywhere from over the TE to stacked behind the DE depending on scouting report.
