Dynasties died when free agency/salary caps were put in place, and the 1995 expansion, so generous to Jacksonville and Carolina, evened everybody up. While there are still incompetent franchises that dwell at the bottom, the offsetting "titanic teams" don't exist anymore. And it was out of those titanic teams that dynasties were born. The only titanic team I've seen since 1995 is New England - the Packers, Colts, Broncos, Steelers, Ravens, whoever, don't compare to the titanic teams of the 60's-80's - free agency and salary caps have killed those type of teams. These teams ARE the best of the last few decades, but they're not titanic. Too much fluidity to maintain potency on both sides of the ball for 7-10 years like in the past. Too many Packer fans have been judging the second best team the last two decades, not as the compare to the actual NFL reality, but against some ideal from 1985. They've done themselves a disservice by having out of whack expectations.

For the Packers being "soft", they are only team to have a winning record against playoff caliber teams played in the regular season, since 1992, at .504. Every other team has a losing record against playoff caliber teams played in the regular season. The Packers' problem is a matter of CONSISTENCY once the post-season starts. I did a fairly thorough analysis between the Packers' regular season stats and post season stats. Some areas actually got BETTER, while there were three declining stats - more giveaways, less takeaways, and a slightly higher rate of surrendering TD's rushing. And the giveaways were by far the biggest factor, and I believe were influential on the other two - instead of being ahead forcing the other team to make mistakes, the Packers were behind and didn't have the ability to force turnovers. And since teams were more ahead than behind in the post-season versus the regular season, they'd run more, hence more rushing TD's on average. So the Packers lived/live by the turnover margin, they just *****'ed their formula come the playoffs.
And what would cause this sudden shift? Lack of preparation and the ability to handle the pressure of the single elimination. In other words, the Packers CHOKED. How is this? The Packers weren't always losing to infinitely better teams in the playoffs, they'd lose to teams near parity or worse. Favre released his inner Jay Cutler too often, and McCarthy releases his inner Marty Schottenheimer too often.
Gratefully, the Packers have won somethings along the line, and the Packers are the tied with the Steelers for the 2nd best overall "playoff worth" behind New England, but the Packers should be between the two. The Packers choked a little too often. Not rolling around on the floor, purple as a grape type choking (like the Vikings) but a corn nut in the windpipe. But it stands the Packers should have been to about five Super Bowls and probably 3-2 in those appearances. But they choked. It wasn't a lack of anything other than consistency and handling the pressures of single elimination.
