Playing their third consecutive home game, the Patriots tried to improve their record to 15-0 against the 1-13 Dolphins. For the first time of the season, 15-year wide receiver Troy Brown was active; he saw action early in the game, returning a Dolphins punt on their first drive 10&#160;yards. The Patriots' second first down of their first possession was their 349th of the season, breaking their 1994 franchise record. Six plays later, Brady connected with Moss for an 11-yard touchdown and a 7-0 Patriots lead. After three punts, the Patriots' third drive of the game began on the final play of the first quarter, a 51-yard Maroney rush to give the Patriots the ball at the Dolphins' 28-yard line. After a successful third-down conversion, Brady threw his second touchdown pass of the game to Moss from a yard out to give the Patriots a 14-0 lead. The Dolphins' punted again on their next drive, and the Patriots opened up a 21-point lead with a 59-yard Maroney touchdown run while also setting the franchise record for net yards on a season, breaking the record of 5,965 set in 1978. After the Dolphins' fourth three-and-out of the game, a 38-yard Brandon Fields punt was muffed by Troy Brown and recovered by the Dolphins, who punted again three plays later. After moving the ball from their own 20-yard line to the Dolphins' 48-yard line, Brady completed a 48-yard touchdown pass to Gaffney on the Patriots' 71st touchdown of the season, breaking the NFL record of 70 set by the 1984 Dolphins. The Dolphins drove the Patriots' 4-yard line with 21&#160;seconds remaining in the half, but Tedy Bruschi batted down a Lemon pass on fourth down intended for Justin Peelle to preserve the Patriots' 28-0 lead heading into halftime. On the opening drive of the second half, Welker caught his 101st pass of the season, tying the Patriots individual franchise record Brown set in 2001. On the next play, Brady was intercepted by Jason Allen the end zone on a pass intended for Moss. After a 22-yard Chatman rush began the Dolphins' ensuing drive, the Dolphins punted for the seventh time three plays later. On third down from their own 28-yard line, Brady threw his second interception of the game, this time picked off by linebacker Derrick Pope on a pass also intended for Moss. The Dolphins moved the ball on their next drive from their own 46-yard line to the Patriots' 1-yard line, where Lemon scrambled out of bounds short of the end zone on 4th and goal. The Dolphins challenged the ruling, which was upheld after review. The play gave the Patriots the ball from their own 1-yard line, where a three-and-out set up a 64-yard Hanson punt from the end zone, his longest of the season. A 22-yard Lorenzo Booker rush on the Dolphins' next possession helped bring the Dolphins' to the Patriots 21-yard line, where Lemon connected with Greg Camarillo to cut the Patriots lead to 28-7. The Patriots committed their fourth turnover of the game when Brady was strip-sacked by Joey Porter to give the Dolphins the ball at their own 28-yard line. Four punts and a scoreless fourth quarter later, the Patriots picked up their 15th win of the season as they improved to 15-0 and became the first 15-0 team in NFL history. The Patriots' 15th win matched the win totals of the 2004 Pittsburgh Steelers, 1998 Minnesota Vikings, 1985 Chicago Bears, and 1984 San Francisco 49ers, while their 15-0 regular season start was a first in NFL history. The Patriots' 6-0 record against division opponents was a franchise first. The win also marked the Patriots' 18th straight regular season victory since their December 2006 loss to the Dolphins, tying the Patriots' 2003-2004 NFL record..
