Our Metrics Explained

What is DVOA?

Defense-adjusted Value Over Average

Measures a team's efficiency by comparing success on every single play to a league average based on situation and opponent.

What is DYAR?

Defense-adjusted Yards Above Replacement

Compares the performance of each player, in terms of DVOA, to a replacement-level baseline rather than the league average for that position.

What is DAVE?

DVOA Adjusted for Volatility Early

Used early in the year with the goal of getting the best idea of how good a team will be over the entire season without jumping to conclusions based on one or two good or bad early games.
