Most of Dallas’s metrics are roughly the same as they were last season, with the major exception of the passing game (and some faulty special teams). Last year, in QB Dak Prescott’s first NFL season, he led the Cowboys to the sixth-most
expected points added (EPA) through the air of any offense in football — a highly effective complement to Dallas’s second-ranked running game. But although the Cowboys still rank among the top five in rushing EPA, Prescott and the passing offense has fallen to 19th in the league in EPA. Prescott’s
traditional numbers aren’t bad, but he’s all but stopped throwing the deep ball and the Dallas receivers are picking up very few yards after the catch. The result has been an aerial attack that struggles to move the chains, keeping the Cowboys from scoring as many points as they should./quote]
