We've been significantly better defensively, and a lot of this can be attributed to our much improved PK. It is alarming how lousy our offensive numbers have been (although some of that can be attributed to a certain line's lack of production).
Luongo has been absolutely amazing these playoffs. He hasn't had to carry the team on his back, but he's definitely gotten back to his clutch form.
This is the first year we've had less GF/G than GA/G and its the best we've done... so the secret to our success is letting in more goals than our opponents. Extrapolating with stats is fun.
A lot of that is due to games 4 and 5 of the Chicago series where we were blown out 12-2. Eliminate those 2 games and our GF is 2.55 and our GA is 1.91. Our GF still isn't that great, but our GA is amazing.
Unfortunately we can't any more than Detroit can take away 2 of their own losses. But we can take the bounce back as a good sign.
Of course you can -- statistics are there to inform and averages are only one way to go. Take the median GA instead of the average and that will basically minimize the impact of the outlier games and give you a better idea of what to expect.
