A week after facing the undefeated Cowboys, the Patriots squared off against the winless Dolphins. The Patriots took the opening drive of the game 80&#160;yards and capped it off with a 30-yard touchdown pass from Brady to Stallworth. After Dolphins quarterback Cleo Lemon fumbled to give the Patriots the ball on the Dolphins' 28-yard line, the Patriots took a 14-0 lead with a 2-yard touchdown reception by Kyle Brady. The Dolphins cut the lead in half with a 4-yard Lemon touchdown run to end a 79-yard drive early in the second quarter, but Willie Andrews returned the ensuing kickoff 74&#160;yards to give the Patriots another 14-point lead. Following a Dolphins punt, a 36-yard Welker reception set up a 35-yard Moss touchdown catch. After another Dolphins punt, Brady connected with Moss on a 50-yard touchdown strike, giving the Patriots a 35-7 lead. An exchange of punts left the Dolphins with the ball at their own 1-yard line, but a 49-yard punt by Brandon Fields and a holding penalty on Kelley Washington gave the Patriots the ball at their own 29-yard line. Still, Brady led the Patriots on another scoring drive, ending this one on a 14-yard Welker catch to give the Patriots a 42-7 lead going into halftime. The 42 points scored in the half were a franchise record. In the second half, the Dolphins drove to the Patriots' 19-yard line on a drive that spanned more than nine minutes, but a Gay interception retained the Patriots' 42-7 lead, one that remained for the duration of the third quarter. Following a Patriots punt, the Dolphins began a 10-play, 80-yard drive that ended on a 1-yard Patrick Cobbs touchdown run early in the fourth quarter, cutting their deficit to 28 points. The Patriots replaced Brady with backup Cassel on the next drive, but after Cassel threw an interception to defensive end Jason Taylor which Taylor returned for a touchdown, Brady returned for the Patriots' next possession. That drive spanned 59&#160;yards and ended with a 16-yard Welker touchdown catch, Brady's sixth touchdown pass of the game, a Patriots record. On their penultimate drive of the game, the Dolphins drove 75&#160;yards and ended the game's scoring with a 7-yard Jesse Chatman touchdown run. The Patriots ran the clock to within two minutes before punting; Lemon ended the game with a 12-yard sack by Seau near midfield. With their 49-28 win, the Patriots began a season 7-0 for the first time in team history.  During the game, Tom Brady earned the first perfect passer rating of his career.
