It's time to let go of the 2012 defense comparisons. I mentioned this in another thread and the numbers that team defense gave up that year was historically great. Look it up, I'm not doing all your homework for you! But it was the best defense over 102 games this century and likely longer than that. They gave up 170 goals in the regular season and only 30 goals in 20 playoff games. 200 total goals in 102 total games. Unless I missed something, there is no team that let in fewer goals in total or an average over the course of regular season + playoffs, including the dead puck era.
FYI, did anyone read the Sports Illustrated article of the Cup issue? It specifically says that during the Olympic break, Sutter was plotting on how to dethrone the Blackhawks and decided that the best way was not to try and contain them and play bend but don't break, but to attack them and throw offense right back in their face. I thought it was an interesting read.
