Just my two pennies. This team (throughout its four years), more than any other I've seen at any level, is a bit of a head case. It has great skill and talent but for whatever reason the slightest bit of adversity rattles it to the point that it can't dig out of holes and close out games in hostile environments. Combine that with just dumb bad luck with injuries and suspensions in recent years (Brekke, Schuler, Huff, Traylor, etc.) and inconsistent foul shooting (one game they knock down 99 percent of their shots the next they can't throw it in the ocean) and you have an even greater up-hill battle.
It's like they read their own headlines and message board fodder, both positive and negative, and let that affect their play. The only thing I can boil it down to is that it is all psychological.
