I agree Thompson has not done enough yet this offseason on defense. Though the definition of championship caliber is murky at best with the Ravens and a few others winning the big one with middling defenses (16th) in recent memory. (The Packers ranked 7th last year.)

The defense was not bad overall last year, they were also 13th in points allowed which is much more important stat that yards. The problem with this defense is that it very rarely steps up in crunch time when it matters the most, with the NFCCG being the most recent. I still believe the bigger overall problem with this defense is that they are mentally weak and soft. Lets look at the accomplishments of this defense starting in 2009:
2009 - highest scoring game in NFL playoff history, with the Packers losing and the defense giving up 51 points.
2010 - turnover creating machine, everything was good, obviously
2011 - after an historic offensive season, a 15-1 record, a first round bye, the defense allows the NY Giants to score 37 points on the Packers home turf, which by the way was nearly 2 TD's more than the Giants season avg.
2012 - after managing to hold the powerful Minnesota Vikings being QB by a wide receiver to 10 points, off to Candlestick they go and give up 45 points and and an NFL record for rushing yards by a QB in the game. Who was this QB of apparently mammoth proportions? The completely underwhelming and average at best QB Collin Kaepernick.
2013 - I can't really say much here other than the fact that this was a defense completely decimated by injury and the they gave it their best shot but ended up short vs the 49ers again.
2014 - good enough game against a dangerous Dallas team but then...here comes the biggest 2nd half collapse in conference championship history blowing a 16 point halftime lead, and allowing 15 points in the final two minutes of the game to force overtime.
So lets recap:
1. A SB victory, awesome!
2. games where the defense gave up, 51, 45 and 37 points, wtf...
3. NFL record for rushing yards by a QB, wtf....
4. NFL record for largest collapse in conference championship game history, wtf...
people can talk about anything and everything under the sun when it comes to this defense, but there is quite simply one of two things going on here.
1. the defense is soft and mentally weak when the pressure is on.
2. the coaching staff has the defense horribly ill-prepared to compete when the pressure is on
The kinds of things that this defense has been part of in the playoffs are simply unacceptable and do not happen to teams that have the above two things I mentioned. At least not in this quantity. This team has lost in the playoffs 4 of 6 years in rather horribly pathetic and often historic fashion
This is caused by more than just the personnel on the field.
