Final scores are  reasonable predictors of future performance, but game grades like DVOA and WEPA are measurably better

Individually, WEPA was the best game grade tested, beating both DVOA and PFF in descriptive and predictive power

Even when a game grade isn’t as predictive of future performance as other game grades, incorporating it into a blended game grade yields a metric that is more predictive than any individual game grade

Depending on implementation, a game grade that blends Point Differential, WEPA, and PFF tends to perform best
