There is no rush to say the Miami Dolphins have a good defense. Through five weeks, the Dolphins rank 26th in defensive DVOA, sandwiched between the New York Jets and (surprisingly) the Buffalo Bills. Their drive success rate ranks 24th in the league, while their points per drive comes in right around average at 15th. Everything about Miami's defensive profile is average to slightly below -- for now.
While there are still kinks to be worked out, head coach Brian Flores' defense showed signs of legitimate promise against the San Francisco 49ers on Sunday.
