To my eye, dolphins pass to set up the run, and San Fran does the opposite. Both very balanced. Dolphins actually lead the NFL in rushing yards per game. All I know is that in the fourth quarter when the other team is coming from behind, the Dolphins present much more of a challenge. Even today, it was a total fluke that The Niners even got into field goal range. They threw a 4-yard curl to Ayuik and no one tried to tackle him for like 40 yards.
That said, they are both very challenging offenses to stop.
