To this point...
Here's the team's points scored when Zach Wilson has played in an NFL game:
14, 6, 0, 27, 20, 13, 34, 30, 17, 17, 21, 18, 9, 24, 26, 24, 10, 9, 31, 12, 24, 40, 27, 16, 17, 20, 3, 31, 22, 12, 17, 3, 6, 6, 22, 10, 6
So in 25 NFL games played, opponents have held Zach Wilson's team to 6 or fewer points 7 times. Now that's a lot, but that means that 18 out of 25 times (72%), Zach's team managed to score more than 6 points. In fact, they scored 20+ points 16 times out of 25 games (64%), and 6 or fewer just 7 times (28%).
So holding his team to 6 points or fewer is still a really good job by the Pats' D. With, mind you, not a lot of help from their own offense or special teams.
