Wow, some of these numbers, especially scoring are not fantastic.

When Ryan became the Jets’ head coach in 2009, he brought Pettine with him, and Pettine spent four years in charge of the Jets defense, which finished No. 1 in the NFL in scoring defense (14.8 points per game) and total defense (252.3 yards per game) in 2009; sixth (19.0) and third (291.5) in 2010; 20th (22.7) and fifth (312.1) in 2011; and 20th (23.4) and eighth (323.4) in 2012.

When Ryan overhauled his staff after the 2012 season, Pettine went to Buffalo, where the Bills finished 2013 ranked 20th in scoring defense (24.3) and 10th in total defense (333.4).
Let's chart this:
Code:
Year Scoring Yards FOrnk
2009      1      1     1 (GB was #2)
2010      6      3     5 (GB was #2 again)
2011     20      5     2 (GB was 25th)
2012     20      8     9 (GB was 8th)
2013bb   20     10     4 (GB was 31st)
Football Outsiders has those defenses that got scored on as performing pretty well from an efficiency standpoint, down by down. Don't remember that team well, but was that the game that just shut Rodgers down in Buffalo?
