NFL Offensive Efficiency: EPA and Success Rate Explained
NFL Offensive Efficiency: EPA and Success Rate Explained
Total yards alone do not tell the entire story of offensive performance. Expected points added (EPA) estimates the change in expected scoring value created by each play, while success rate gauges consistency.
Why total yards can mislead
A team can gain many yards but fail to finish drives because of turnovers or missed conversions. Another may gain fewer yards yet start drives with favorable field position and score more efficiently.
How to interpret the numbers
EPA per play and success rate complement each other. Their definitions vary by provider, so use consistent methodologies and account for opponent quality, injuries, pace and game script.
Betting analysis
These metrics can inform matchup research, but they are not guaranteed predictors. Any projection must be compared with the market price before assessing whether a wager offers value.
