The average team in the NFL runs the ball on 41.25% of its offensive plays.
The standard deviation from that average is 5.45%.
The Miami Dolphins run the ball on 33.82% of their offensive plays, which is 1.36 standard deviations below the mean, and which places it in the 8.7th percentile in the league, third worst in the league, behind only the Atlanta Falcons (30.35%) and the Cleveland Browns (31.29%).
One might think that teams that run the ball more poorly also run the ball less, and that is supported somewhat by the 0.41 correlation between yards per carry and the percentage of offensive plays accounted for by runs. However, the Dolphins' 4.1 yards per carry is the same as the league average, which suggests the Dolphins are not running the ball less because they're significantly less effective than the average team running the ball.
One might also think that teams that pass the ball more effectively run the ball less, but that isn't supported by the 0.14 correlation between net yards per pass attempt and the percentage of offensive plays accounted for by runs.
The correlation between winning percentage and offensive rushing attempts is 0.55, which is moderately strong, though the difference in rushing attempts for and against is correlated with winning percentage at 0.71, which is very strong.
In my opinion the Dolphins' offense hasn't featured the running game this year enough to: 1) have a rushing attempts differential that is associated with winning, or 2) optimally support the development of Ryan Tannehill.
