The defense has been lackluster, at best. From what I've seen they have been giving up too many second and third chances, and also letting shooters get open in great scoring positions. I described it on the Blues board as too many people playing the puck and not a player in their own end.
They played more than well enough to win yesterday. Rinne was hot in net for the Preds, and on the GWG, after playing pretty well in their own end all day, four players went to the boards for a loose puck leaving only Faulk back. That is a symptom of too many people trying to do too much. Faulk is not the guy you want in that position.
Goaltending has not been spectacular, but has been good enough to win some of these games. But, if teams are going to get second and third chances, or have good looks near the net, the save percentage is not going to fall as a result.
They also need to find somebody who can fill JayBo's shoes, which will not be easy.
