Okay, but in most of their playoff losses since Spygate, the offense is what struggled, not the defense:
17-14 (the greatest offense ever at the time scored 14 pts)
33-14 (the offense had like three or four turnovers in the first Q, leading to the early 24-0 deficit)
28-21 (but this was really a low-scoring game, but both teams scored a lot late...it was 21-14, until the Jets scored after an onside kick late, and NE threw in a garbage score at the very end)
21-17 (the offense was blanked after scoring on the first possession of the 2nd half)
28-13 (the offense was shut out at home in the second half)
26-16 (the offense had 3 points until it was 23-3 Denver in the 4th)
16 points per game from an offense featuring an all-time great QB isn't gonna get it done come playoff time.
