Right now Patriots defense is playing the best of any unit left in the playoffs when it comes to scoring defense. They had a rocky start to season when they started 2-2 and allowed 122 points in 4 games. Since then 12-1 and they have allowed the fewest points of any team (188) over that last 13 games. That is 14 points a game. The highest point total allowed during that stretch is 27 when the Dolphins gave them their lone loss. The next highest is 24 to Pittsburgh.
Minnesota has allowed 200 points in their last 13 games (15.3) and Jacksonville has allowed 222 in their last 13 games (17.0)
Jacksonville got their defensive rating by bullying a bunch of offensively challenged teams and holding them to 10 points or under 9 times. When faced with real offensive teams they got steamrolled and gave up 42, 44, 27 and 27. Minnesota has been a little better during their 12-1 stretch but surrender 30 plus point twice and looked mediocre at the end of Saints game when they allowed 4 scoring drives to end the game.
