The Miami Dolphins made a statement on the first play from scrimmage that they had put their bad showing of a week ago behind them.
Miami set an aggressive tone by opening the game with a deep throw to Ted Ginn Jr., which went for a 45-yard gain to the Bills' 35. The Dolphins went right after Terrence McGee, who was back after missing the past two games with a sprained knee. McGee had pretty good coverage, but Ginn leaped to make a play on the ball.
Miami's offense, which did little in last week's loss to Baltimore, drove 80 yards in nine plays for a touchdown. It came on a 2-yard pass to tight end Anthony Fasano.
Key gains: A 28-yard pass over the middle to Lee Evans set up the Bills' first field goal.
Second-guess: It was a nice first drive for the Bills. But on third-and-goal from the 1, Miami had its two big nose tackles in the middle, and the Bills tried to pound it in. Fred Jackson was stuffed and the Bills settled for a field goal.
Langston Walker knows about defending the bull rush as an offensive tackle. He also knows how to deliver the bull rush. Walker pushed into the middle of the Miami line on a 46-yard field-goal try with 1:44 left in the first half and swatted away Dan Carpenter's attempt. The play preserved Buffalo's 9-7 halftime lead.
It was the sixth field-goal block of Walker's seven-year career. He had five blocks with the Oakland Raiders.
Asked his secret to Sunday's block, the 366-pound Walker said: "Physics."
"I got a good push, and Ryan Denney got good push, and I got a little luck, too," Walker said.
Key plays: Rian Lindell booted field goals of 43 and 47 yards to improve to 15 of 18 on the season.
Second-guess: A dubious third-down call just before the field-goal try could have cost the Dolphins points. On third-and-14 from the Bills 23, Miami put three tight ends in the game and tried a reverse to the lone receiver on the field. Jabari Greer stayed home and made the tackle for a 4-yard loss. It forced a 46-yard try, which came out on a slightly lower trajectory due to the distance.
Coin of the realm
Dick Jauron's philosophy of deferring the choice when he wins the opening coin toss looks like a good one.
For the third time this year, the Bills had a good drive to open the third quarter after opting to receive the second-half kickoff.
The Bills marched 70 yards in eight plays to a touchdown to start the third quarter that gave them a 16-7 lead.
Marshawn Lynch capped the drive with an 8-yard scoring run.
The Bills also scored in St. Louis to open the third quarter, and they got in scoring position against the Raiders in the same situation.
Field flip: The Bills were backed up on their own 14 but Brian Moorman changed the field position with a 56-yard directional punt that went out of bounds at the Miami 31. The defense, however, could not stop Miami on the ensuing drive.
Key plays: The big gainer of the quarter was Chad Pennington's 64-yard strike to Ted Ginn, which set up a field goal.
Wildcat report: Miami used the formation on three plays on its TD drive, and it produced 16 yards.
Porter is stout
There was talk about Dolphins linebacker Joey Porter being on the downside of his career before the season started.
Talk is cheap.
Porter, the 31-year-old outside linebacker discarded by Pittsburgh two years ago, went wild on the Bills in the fourth quarter. He took the ball away from Trent Edwards on a quarterback sneak with 11:49 to play to snuff out a Bills threat. He sacked Edwards in the end zone for a safety with 7:50 to go to give Miami a 22-16 lead.
Asked about being written off in the past, Porter said:
"If you really watch football, know football, you would understand it. You're all just pen pushers. All you see is Joey's not good enough. I told you, you get me in a 3-4 defense, 10 sacks is a given."
Porter, who had 5 1/2 sacks last season, now has 10 1/2 sacks in seven games.
Key plays: The turnovers were decisive. Edwards had an interception and a fumble. Robert Royal fumbled after a 20-yard catch. Roscoe Parrish muffed a punt return in the final seconds.
