Are all the core players on the Blackhawks to blame for the season struggles?

If the core players stay healthy, they will come around and dominate. Something isn't clicking yet, but in time, a spark can and will happen, therefore putting the Blackhawks back into playoff position. Defense really needs to step up their game. Many of the goals against the team have happened because of penalties, therefore one of the most important tasks for the team is to stay out of the box. The team very much has the capability to stay on pace for a full 60 minutes, no less. It's half season, which means there's sufficient time to ignite the spark that gave the Blackhawks a memorable 09-10 season. No, this isn't the 09-10 Blackhawks, but it doesn't mean the Blackhawks can't be playoff contenders at the very least.
