A Fangio-tree defensive package that uses 3-3-5 personnel to present a five-man line (5-1 box) with a single stacked inside linebacker.
The Penny front is a 3-3-5 personnel package and front structure popularized by Vic Fangio and widely adopted across the NFL that presents a five-man line of scrimmage (5-1 box) with only one off-ball inside linebacker stacked behind the line.
Penny provides specific answers against modern passing spread offenses and two-high coverage looks:
Penny, Penny packageMint front, Bear front, Tite frontShown with Penny's 4i-0-4i interior against Inside Zone left. The 4i defenders squeeze B toward A, the nose works both A gaps, the edge linebackers handle C and the stacked linebacker overlaps the first open interior gap.
Some Fangio-tree material uses Eat for a particular front or call inside the Penny package. That language is not portable: other defenses use Eat for an unrelated gap-exchange call against option runs.
