Lamar Miller averaged nearly 5 yards per carry, running 14 times for 69 yards and a touchdown. Charles Clay had five catches for 109 yards and only one carry — a 1-yard TD run with 4:40 left in the third quarter, which turned out to be the game's decisive score and stood up to a replay review.
That, and a staunch defense late was enough for the Dolphins to hold on.
"You have to be balanced to win football games. You can't really win a football game by just throwing the whole game," Wallace said. "You have to mix it up."
The Dolphins didn't shy away from trading jabs, especially after Indy piled up 315 yards of offense in the first half, their highest first-half total in seven years.
The Colts finished with 438 yards, but couldn't put Miami away after taking a 17-14 lead in the first half and a 20-17 lead early in the third quarter after Tannehill's fumble.
But Miami made all the big plays after that — the 34-yard completion from Tannehill to Wallace that set up Clay's rushing score, the third down conversions to keep Luck & Co. off the field and the two big fourth-quarter stops.
"Our guys wanted to play them, we wanted to compete," Miami coach Joe Philbin said. "They were ready for a 60-minute game and we knew we would have to make some plays to win."
