Answer based on context:

In a game that was hyped as a potential Super Bowl preview, the Patriots rolled into Lambeau Field to face Aaron Rodgers and the red hot 8-3 Packers who were 6-0 at home, in a game that lived up to the hype. This was the first matchup between Rodgers and Brady, as Rodgers missed the 2010 contest at Gillette Stadium with a concussion. On the opening drive of the game, the Packers drove all the way to the Patriots 14, but the Patriots red zone defense continued to stay hot and forced them to settle for a 32-yard field goal by Mason Crosby. After a Patriots punt, the Packers, aided by a 33-yard completion from Rodgers to Davante Adams, reached the Patriots 17, but once again the Patriots defense kept them out of the end zone and Mason Crosby kicked a 35-yard field goal, increasing the Packers lead to 6-0. After a Patriots three-and-out, the Packers stormed 85 yards in only 4 plays with Rodgers finding Richard Rodgers deep for a 45-yard touchdown pass, increasing the lead to 13-0. After a terrible first quarter, the Patriots got things going on their next drive. On the first play of the second quarter, Tom Brady darted a pass to Gronkowski for a 29-yard gain to the Packers 41. Three plays later Brandon Bolden scampered for a 6-yard touchdown, trimming the deficit to 13-7. The Patriots defense responded by getting the Packers to a 3rd-and-5, but no pass rush allowed Rodgers 14 seconds to find Randall Cobb for a 33-yard gain to the Patriots 34. The Packers reached the Patriots 6, but Hightower sacked Rodgers for a 9-yard loss on 3rd-and-goal, and Crosby kicked a 33-yard field goal with just under six minutes remaining in the first half. Down 16-7, Brady drove the Patriots back down the field again on an 80-yard drive, finding LaFell in the back of the end zone for a 2-yard touchdown pass, trimming the score to 16-14. However, 1:05 would prove to be too much time for Aaron Rodgers. After an incompletion to Adams, Rodgers threw a screen pass to James Starks who took it 28 yards to the Packers 47. An 8-yard completion to Jordy Nelson moved the ball to the Patriots 45. Two plays later, Rodgers hit Nelson in stride, who outran Revis and McCourty, for a 45-yard touchdown with 00:14 remaining in the first half, increasing the lead to 23-14. That was only the 2nd touchdown Revis allowed all season. The third quarter was a stalemate, as both defenses began to take over and neither team scored. The Patriots took over with 2:21 remaining in the third and constructed a 9 play, 78-yard drive with Brady throwing a laser to LaFell for a 15-yard touchdown early in the fourth quarter, pulling the Patriots within two, 23-21. The Packers countered, reaching the Patriots 10, but Adams dropped a sure touchdown on a wide-open slant on 3rd-and-5, but Crosby kicked a 28-yard field goal, making the score 26-21 with 8:41 remaining. On their next drive, Brady converted a 4th-and-3 to Edelman at their own 49, and two plays later converted a 3rd-and-7 with a 10-yard pass to Gronkowski. Three plays later, Brady dropped a pass into the arms of Rob Gronkowski who caught the ball momentarily, but Ha'Sean Clinton-Dix punched it out before it could be ruled a catch, wiping out a touchdown. On the very next play, Mike Daniels and Mike Neal combined to sack Brady for a 9-yard loss. Instead of calling a timeout Gostkowski was sent out on the field for a 47-yard field goal attempt with the clock running to preserve a timeout at the two-minute warning, but Gostkowski missed the hurried field goal attempt, keeping the score 26-21 with just 2:40 remaining. The Patriots forced a 3rd-and-4, but Rodgers converted it with a 7-yard pass to Cobb, enabling the Packers to run out the clock and win the game. The Patriots fell to 9-3 with the loss, snapping their 7-game winning streak. The Patriots looked nothing like the team that had won 7 straight games, struggling in all facets of the game. Tom Brady was 22 of 35 for 245 yards 2 touchdowns and no interceptions. The Patriots managed 84 yards rushing, but only carried the ball 19 times.  Rob Gronkowski was the receiving star for the Patriots with 7 catches for 98 yards.  Aaron Rodgers, continuing his home dominance, turned in another great performance, completing 24 of 38 passes for 368 yards, two touchdowns, and no interceptions, benefiting from the Patriots almost non-existent pass rush. They managed three sacks, but couldn't get any consistent pressure. Meanwhile, Eddie Lacy had 98 yards on 21 carries. Davante Adams was the receiving star for the Packers with 6 catches for 121 yards.
