The notion that this defense is better than 2006 or 2007 is arguable, for sure. Personally, I think it's borderline absurd. People sure have short memories around here. Even the author's number charts show that the defenses of 2006 and 2007 were much better in yards allowed per drive, the number of plays per drive, the amount of points allowed, and the amount of turnovers caused.
Oddly enough, he titles the article "best defense in a decade," but clearly chooses to look past those dominant years in order to cherry pick the stats. Instead, the majority of the focus is on the rebuilding years of 2009--2013.
2006---14.8 points allowed (2nd in NFL)
--Allowed only 10 touchdowns via the air (#1), with 22 interceptions
--Top 10 in a) scoring, b) yards, c) first downs, d) turnovers caused, e) touchdowns given up both through the air and ground, f) YPC average in rush defense
--Front seven of Seymour, Warren, Wilfork, Bruschi, Vrabel, Colvin, Green, Wright, etc was very strong
--Asante Samuel had TWENTY FOUR passes defended and TEN interceptions
----------------------------------------------------------------------------------------------------------
2007---17.1 points allowed (4th in NFL)
--Top 10 in a) scoring, b) yards, c) first downs, d) turnovers caused, e) touchdowns on the ground, and this was all during lots of garbage time
--Seymour, Wilfork, Warren, Adalius Thomas, Vrabel, Seau, Harrison all legendary supporters
--While Samuel's #s didn't quite live up to the insane bar set in 2006, he still somehow managed to defend 18 more passes with another 6 interceptions
