NPC, I would argue that theyre a stronger defensive team at this point than last year.  It has taken some time with all of the rookies but they are running around less in their own zone by being better positioned...heck, Zairsev alone makes them a better defensive team.  
Without Bozak they lack the crucial defensive end faceoff win but that will come in time with the goat and mathews.
And Anderson, far better goalie than Reimer...yes Reimer had a good run last year but look at his numbers this year.  Its easy to cherry pick stats to try and make an argument.
