It's the 10th time in the Bill Belichick era that the Patriots have won the AFC East.
New England's ninth win was a tough one. Brady struggled against the Dolphins' defense, completing just 60 percent of his passes for 238 yards and a touchdown. He also threw an interception. He had his worst quarterback rating (74.8) of the season.
Miami held New England to 321 yards on offense. The Dolphins couldn't get much offense going either, picking up 277 yards. Each team had one turnover.
The Patriots will have one of their biggest challenges this season when they host the Houston Texans (11-1) next Monday.
