a 20-yard reception by receiver Howard Twilley, but the drive stalled and ended with no points after kicker Garo Yepremian missed a 49-yard field goal attempt. Starting with 6:15 left in the period, Dallas drove 76 yards in 10 plays, including a 21-yard reception by Lance Alworth and Calvin Hill's three carries for 25 yards, and then scored on a 7-yard touchdown pass from Staubach to Alworth to increase their lead to 10–0 (Alworth would refer to the receptions that he made on the scoring drive as "The two most important catches of his career"). Miami started the ensuing drive with just 1:15 left in the half, and quarterback Bob Griese completed three consecutive passes, two to receiver Paul Warfield and one to running back Jim Kiick, for 44 total yards to reach the Dallas 24-yard line. On the next play Griese threw to Warfield, who was open at the 2-yard line, but the ball was deflected by Green and bounced off Warfield's chest. Miami had to settle for Yepremian's 31-yard field goal to cut the Dolphins deficit to 10–3 going into halftime. Third quarter But Dallas dominated the second half, preventing any chance of a Miami comeback. Dallas reasoned that Miami would make adjustments to stop the Cowboys' inside running game which had been so successful in the first half. So the Cowboys decided to run outside. The Cowboys opened the third period with a 71-yard, 8-play drive, which included four runs by Thomas for 37 yards, a reverse by Hayes for 16 yards, and only one pass, scoring on Thomas' 3-yard sweep to make the score 17–3. This seemed to fire up the Dallas defense, who managed to prevent Miami from getting a single first down in the entire third quarter. The farthest advance Miami had in the third quarter was to its own 42-yard line as Griese and the offense were, as Don Shula put it, "destroyed." On an incomplete pass, Jake Scott hit Roger Staubach on a blitz that shook him up late in the third quarter, but Staubach returned in the fourth. Fourth quarter Miami managed to advance to midfield early in the final period, opening the fourth quarter with their first third down conversion of the game. Howley ended the drive, however, by intercepting a pass from Griese intended for Kiick in the flat. After returning the ball 41 yards, Howley tripped and fell
