The biggest single problem with our goaltending has been the "untimely" goal. Either early in a game when momentum is in the Canes favor, our netminders have a history of giving up the softie that kills that momentum. It is especially deflating for a young team.
Another type of untimely goal is the the one that cuts a two goal lead to a one goal lead. It, too, has historically been of the soft variety...or maybe more importantly, a goal that shouldn't have happened...bad bounce, off of a skate (yes, Ron Hainsey, I'm looking at you), or one the goaltender just would have wanted back.
Then, of course, the late in the game, "barrage of shots" variety. This has become a killer for the Hurricanes. Recently, primarily this season, the team has developed a "protect the lead" defense mentality that is more like "going into a shell" than "protect at all costs". I think it was Bill Parcells that said, prevent defenses prevent you from winning. Of all of their blown-lead losses this year, only one (Winnipeg) was because they played foolishly aggressively and made mistakes because of "commission" as opposed to mistakes of "omission".
As some have said, it is a young team that is still learning how to win. Give it time and the record will catch up to the advanced stats. That said another skilled 1st line player and a big body with scoring touch for the 3rd line would do wonders for this team's results.
