Answer based on context:

The defenses dominated the first three drives of the game, all ending in punts. But midway through the first quarter, Malcom Brown and Patrick Chung shared a tackle of Kenneth Dixon in the end zone for a safety(the third by the Patriots' defense on the season). The Ravens forced the Patriots to punt, and, aided by a 40-yard gain from Joe Flacco to Kyle Juszczyk and a 15-yard pass interference penalty on Cyrus Jones, drove all the way to the Patriots 16, but Shea McClellin blocked Justin Tucker's field goal attempt. Following that, the Patriots covering 74 yards in 10 plays, scoring on a 1-yard touchdown run by Blount, his 14th, which tied him with Curtis Martin who had 14 for the 1995 New England Patriots. The Ravens reached Patriot territory on their following possession, too, but punted again. Aided by a 61-yard completion to White, the Patriots raced 89 yards in just eight plays with Brady finding Mitchell on a 6-yard touchdown pass, extending the lead to 16-0. On the second plays of the Ravens next drive, McCourty intercepted Flacco at the Patriots 22 and returned it 40 yards to the Ravens 38, but official review ruled him down by contact at the Patriots 23. Despite this, the Patriots reached the Ravens 1-yard line, but Eric Weddle intercepted Brady(only his second interception of the season) and returned it 14 yards to the Ravens 10. Two possessions later, after Devin Hester returned a punt 12 yards to the Ravens 28, the Ravens reached the Patriots 28 and got on board with a 50-yard Tucker field goal with 0:11 seconds left in the half, making the score 16-3 at halftime. After forcing the Ravens to punt on the initial drive of the third quarter, the Patriots marched 65 yards to score on Brady's 19-yard pass to Bennett, increasing the lead to 23-3. A 6-yard run by Blount on the drive game him 1,005 yards for the season. However, the Ravens got back in the game with aide from the Patriots. While the Ravens offense continued it's ineptitude, Cyrus Jones muffed a punt with Chris Moore recovering at the Patriots 3. Two plays later, Flacco connected with Darren Waller for a two-yard touchdown pass, trimning the deficit to 23-10. Things got better for the Ravens with Matthew Slater fumbling the kick return and Shareece Wright recovering at the Patriots 22-yard line. Four plays later, Dixon caught a swing pass for an 8-yard touchdown, and all of a sudden the score was 23-17. After three consecutive punts, the Ravens, aided by a 47-yard catch by Breshad Perriman, reached the Patriots 12, but on 3rd-and-4 Flacco was sacked by Ninkovich for an 8-yard loss. Tucker finished the drive with a 38-yard field goal, trimming the deficit to 23-20 with 6:35 remaining in the game. On the first play of the Patriots next drive, Brady found Chris Hogan wide open for a 79-yard touchdown, extending the Patriots lead to 30-20. That was Brady's 450th career touchdown pass and only Hogan's second career 100-yard receiving game. Yet, the Ravens were still in the game, driving to the Patriots 20-yard line, Tucker hit a 37-yard field goal, trimming the deficit to 30-23 and giving the Ravens a chance. On the Patriots next drive, the Ravens brought the game to a 4th-and-1 with 0:13 remaining. Instead of punting, the Patriots went for the kill shot and got it with Blount's 3-yard run enabling the Patriots to run out the clock and end the game. The Patriots improved to 11-2 and dropped 496 yards of total offense and 30 points on the Ravens' top-ranked defense, both the most allowed in the season by the Ravens. The Patriots posted their 10th all-time franchise victory against the Ravens. This was Brady's 100th career home win and his 9th 400+ yard passing game of his career and his second of the season.
