But this victory had defense written all over it. The numbers were staggering, really.
The Dolphins held Buffalo to only 118 total yards, eight first downs and came up with four sacks and three interceptions.
This was a Buffalo offense that helped the Bills score 69 points in their first two games.
But the only way the Bills would score on this night when was Nate Clements stepped in front of James McKnight on a outside pass, picked off a Jay Fiedler pass and returned it 54 yards to make the score 10-7 early in the fourth quarter.
But after Olindo Mare missed his second field goal attempt of the evening, the Dolphins held Buffalo without a first down, then clinched the victory with a 51-yard drive that ended with Williams' 1-yard touchdown run.
Chris Chambers scored Miami's other touchdown on a 12-yard pass from Fiedler late in the second quarter. Mare made it 10-0 with a 26-yard field goal midway through the third quarter.
The victory gave the Dolphins a 2-1 record, tying with Buffalo and New England atop the AFC East.
It's a great way for the Dolphins to head into their bye week.
