Bendability is the first indicator on Planet Pigskin that attempts to measure the concept of the "bend but don't break defense." But remember, the Bendability Index is not merely an defensive indicator! It is a team-wide measurement of ability to keep opponents off the scoreboard. It takes into account a variety of factors (including proficiency of offense and special teams, red zone defense, and turnover differential) and then spits it all out in an easy-to-understand number. Other measures of defense, and defensive efficiency, look at the defensive unit in a vacuum. We do not care how a unit plays in a fantasy-football vacuum because in real football games teams do not play in a vacuum. Instead, our Quality Stats give you insight into the many complex, interacting factors that go into team-wide success.
Bendability is obtained this way: Yards Allowed/Total Points Allowed = Yards Per Point Allowed (YPPA). The higher the number, the more difficult a team makes it for opponents to score points.
