"I thought our defense played an outstanding game," Sherman said. "We put pressure on their quarterback. We stifled their running game, and they have a great running game."
Favre made his 165th consecutive start wearing a brace and went 16 of 25 for 187 yards with one touchdown pass in helping the Packers improve to an NFL-best 7-1.
"It's not too bad," Favre said. "It's a little stiff. I survived. The brace hindered me a little bit. I knew it would, but overall it served its purpose."
Favre was sacked twice but emerged from the contact unfazed.
"It didn't bother me. It's OK when the little guys hit you," Favre said.
The Packers also got 143 yards in total offense out of running back Ahman Green, logged four takeaways and limited Miami running back Ricky Williams to 47 yards on 14 rushes.
"When you get beat 4-1 in turnovers on the road you aren't going to win," said Miami coach Dave Wannstedt, who dropped to 0-7 at Lambeau Field.
Things didn't start out as well as they ended for Favre.
The Packers' first drive ended when Favre threw an interception - his only one of the game - in the end zone. Green Bay recovered and led 14-0 at half thanks to a pair of Green touchdown runs.
Ryan Longwell made it 17-0 in the third quarter with a 27-yard field goal.
Sharper put an exclamation point on the prime time rout when he intercepted a Ray Lucas pass and returned 89 yards for a touchdown.
"They ran that play earlier in the red zone, and I said if I see that again, I'm going to go for it," Sharper said.
Miami accounted for the final with a 46-yard field goal by Olinda Mare and a 1-yard TD run by Lucas in the fourth quarter. Favre exited the game in the fourth quarter with the crowd chanting "MVP! MVP! MVP!"
The Packer victory made the return of wide receiver Cris Carter inconsequential.
The 37-year old former Viking caught three passes for 31 yards but he fumbled twice.
"That's just part of not playing. I didn't see him and I didn't feel him," Carter said.
